ARM: orion5x: Revert commit 4904dbda41c8.

It is not valid for orion5x to use mac_pton().

First of all, the orion5x buffer is not NULL terminated. mac_pton()
has no business operating on non-NULL terminated buffers because
only the caller can know that this is valid and in what manner it
is ok to parse this NULL'less buffer.

Second of all, orion5x operates on an __iomem pointer, which cannot
be dereferenced using normal C pointer operations. Accesses to
such areas much be performed with the proper iomem accessors.

ARM: orion5x: only call into phylib when available

Board code cannot call mdiobus_register_board_info() when phylib
or mdio_device is a loadable module:

arch/arm/plat-orion/common.o: In function `orion_ge00_switch_init':
:(.init.text+0x474): undefined reference to `mdiobus_register_board_info'

I had a number of ideas for how this could be solved, but after the MDIO
code got split out from PHYLIB it has gotten too hard, so I'm basically
giving up, and only call the mdiobus_register_board_info() function
if the MDIO layer is built-in to avoid the link error. This is similar
to how we handle PHY registration on other ARM platforms.

ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
now be selected directly.

- "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".

Making the select itself conditional avoids the warning and
makes the kernel slightly smaller as the compiler will be
able to drop the unused board info.

This commit converts the LaCie d2 Network platform to the Device Tree.

All devices except LEDs are converted, because the LED code needs a
non-LED GPIO to be set to a given value for the LEDs to work, and this
cannot yet be easily represented in DT.

Also, references to the LaCie Big Disk Network platform are lost,
because this platform apparently has exactly the same hardware support
as the LaCie d2 Network, so their Device Tree files would be
identical.

It is worth noting that:

* The PCI description for the DT case is kept in board-rd88f5182.c.

* The existing non-DT support in rd88f5182-setup.c is kept as is, in
order to allow testing of a given platform in both DT and non-DT
cases. It will ultimately be removed, once we no longer care about
non-DT support for Orion5x.

ARM: orion5x: switch to DT interrupts and timer

This commit switches the Orion5x platforms described through DT to use

This involves:

* Describing in the DT the bridge interrupt controller, which is a
child interrupt controller to the main one, which is used for timer
and watchdog interrupts.

* Describing in the DT the timer.

* Adding in the DT the interrupt specifications for the watchdog.

* Selecting the ORION_IRQCHIP and ORION_TIMER drivers to be compiled.

* Change board-dt.c to no longer have an ->init_time() callback,
since the default callback will work fine: it calls
clocksource_of_init() and of_clk_init(), as needed.

* Implement a multi-IRQ handler for non-DT platforms in
mach-orion5x/irq.c.

Once reprogramed, we can tell the kernel to (re)enable things
by checking the FPGA ID against a lookup table for what a
particular FPGA bitstream can provide.
