ARM: samsung: Remove HAVE_S3C2410_I2C and use direct dependencies

A separate Kconfig option HAVE_S3C2410_I2C for Samsung SoCs is not
really needed and the i2c-s3c24xx driver can depend on Samsung ARM
architectures instead. This also enables i2c-s3c2410 for arm64 Exynos
SoCs, which is required for example by Exynos850.

This is basically continuation of work made in following commits:
- commit d96890fca9fd ("rtc: s3c: remove HAVE_S3C_RTC in favor of
direct dependencies")
- commit 7dd3cae90d85 ("ARM: samsung: remove HAVE_S3C2410_WATCHDOG and

arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL

ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
which in turn enables memmap_valid_within() function that is intended to
verify existence of struct page associated with a pfn when there are holes
in the memory map.

However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID
and arch-specific pfn_valid() implementation that also deals with the holes
in the memory map.

The only two users of memmap_valid_within() call this function after
a call to pfn_valid() so the memmap_valid_within() check becomes redundant.

Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely
entirely on ARM's implementation of pfn_valid() that is now enabled
unconditionally.

The "HAVE_xxx_WATCHDOG" pattern of dependency is not popular and Samsung
platforms are here exceptions. All others just depend on
CONFIG_ARCH_xxx.

This makes the code slightly smaller without any change in
functionality.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
is now selectable by everyone, so we need not declare our
intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

ARM: use "depends on" for SoC configs instead of "if" after prompt

Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.

Please notice the difference between

config ARCH_FOO
bool "Foo SoCs" if ARCH_MULTI_V7

and

config ARCH_FOO
bool "Foo SoCs"
depends on ARCH_MULTI_V7

These two are *not* equivalent!

In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns. This is probably not what
you want.

The former should be used only when you need to do so, and you really
understand what you are doing. (In most cases, it should be wrong!)

For enabling/disabling sub-architectures, the latter is always correct.

As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).

[Arnd: I note that there is not really a bug here, according to
the discussion that followed, but I can see value in being consistent
and in making the lines shorter]

ARM: samsung: make SAMSUNG_DMADEV optional

The only remaining driver using the samsung dmadev code is the broken
samsung-ac97 sound driver. However, as found by Russell's autobuilder,
the elaborate dependency chains around it cause problems with
circular dependencies.

This is an attempt to simplify those dependencies by making the
SAMSUNG_DMADEV option user-selectable. I also try to keep the
default settings for all related options unchanged, so we don't
introduce any regressions against earlier testing on linux-next.

In particular, all s3c64xx and s5p* platforms keep selecting the
pl330 and pl08x drivers they require, but the select statement
is now moved towards the main platform option, and it remains
optional by unselecting CONFIG_DMADEVICES.

ARM: config: sort select statements alphanumerically

As suggested by Andrew Morton:

This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.

Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically. This commit was
created by the following perl:

while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

We have four testers reporting success of this change (Tony, Stephen,
