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.

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.

Use map_physmem() and unmap_physmem() to convert from physical to
virtual addresses. This gives the arch a chance to provide an uncached
mapping for flash accesses.
Signed-off-by: NHaavard Skinnemoen <hskinnemoen@atmel.com>

map_physmem() returns a virtual address which can be used to access a
given physical address without involving the cache. unmap_physmem()
should be called when the virtual address returned by map_physmem() is
no longer needed.

This patch adds a stub implementation which simply returns the
physical address cast to a uchar * for all architectures except AVR32,
which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any
architecture needs to do such mappings through the TLB, this is the
hook where those TLB entries can be invalidated.

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.

This adds implementations of __raw_read[bwl] and __raw_write[bwl] to
m68k, ppc, nios and nios2. The m68k and ppc implementations were taken
from Linux.

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.

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.)
