cfi_flash: Add manufacturer-specific fixups
Run fixups based on the JEDEC manufacturer ID independent of the
command set ID.
This changes current behaviour: Previously, geometry reversal for AMD
chips were done based on the command set ID, while they are now done
based on the JEDEC manufacturer and device ID.
Also add fixup for top-boot Atmel chips. A fixup is needed for
AT49BV6416(T) too, but since u-boot currently only reads the low byte
of the device ID, there's no way to tell it apart from AT49BV642D,
which should not have this fixup. Since AT49BV642D support is
necessary to get ATNGW100 board support into mainline, I've commented
out the fixup for now.

cfi_flash: Add cmdset-specific init functions
Move things like reading JEDEC IDs and fixing up geometry reversal
into separate functions. The geometry reversal fixup is now performed
by altering the qry structure directly, which makes the sector init
code slightly cleaner.

cfi_flash: Read whole QRY structure in one go
Read out the whole CFI Standard Query structure after successful cfi
identification. This allows subsequent code to access this information
directly without having to go through flash_read_uchar() and friends.

cfi_flash: Introduce read and write accessors
Introduce flash_read{8,16,32,64) and flash_write{8,16,32,64} and use
them to access the flash memory. This makes it clearer when the flash
is actually being accessed; merely dereferencing a volatile pointer
looks just like any other kind of access.

cfi_flash: Reorder functions and eliminate extra prototypes
Reorder the functions in cfi_flash.c so that each function only uses
functions that have been defined before it. This allows the static
prototype declarations near the top to be eliminated and might allow
gcc to do a better job inlining functions.

cfi_flash: Break long lines
This patch tries to keep all lines in the cfi_flash driver below 80
columns. There are a few lines left which don't fit this requirement
because I couldn't find any trivial way to break them (i.e. it would
take some restructuring, which I intend to do in a later patch.)
