Move the bcm963xx Image Tag parsing into its own partition parser. This
Allows reusing the parser with different full flash parsers.
While moving it, rename it to bcm963* to better reflect it isn't chip,
but reference implementation specific.

The Sharp SL Series (Zaurus) PXA handhelds have 16/64/128M of NAND flash
and share the same layout of the first 7M partition, managed by Sharp FTL.
GPL 2.4 sources: http://support.ezaurus.com/developer/source/source_dl.asp
The purpose of this self-contained patch is to add a common parser and
remove the hardcoded sizes in the board files (these devices are not yet
converted to devicetree).
Users will have benefits because the mtdparts= tag will not be necessary
anymore and they will be free to repartition the little sized flash.
The obsolete bootloader can not pass the partitioning info to modern
kernels anymore so it has to be read from flash at known logical addresses.
(see http://www.h5.dion.ne.jp/~rimemoon/zaurus/memo_006.htm )
In kernel, under arch/arm/mach-pxa we have already 8 machines:
MACH_POODLE, MACH_CORGI, MACH_SHEPERD, MACH_HUSKY, MACH_AKITA, MACH_SPITZ,
MACH_BORZOI, MACH_TOSA.
Lost after the 2.4 vendor kernel are MACH_BOXER and MACH_TERRIER.
Almost every model has different factory partitioning: add to this the
units can be repartitioned by users with userspace tools (nandlogical)
and installers for popular (back then) linux distributions.
The Parameter Area in the first (boot) partition extends from 0x00040000 to
0x0007bfff (176k) and contains two copies of the partition table:
...
0x00060000: Partition Info1 16k
0x00064000: Partition Info2 16k
0x00668000: Model 16k
...
The first 7M partition is managed by the Sharp FTL reserving 5% + 1 blocks
for wear-leveling: some blocks are remapped and one layer of translation
(logical to physical) is necessary.
There isn't much documentation about this FTL in the 2.4 sources, just the
MTD methods for reading and writing using logical addresses and the block
management (wear-leveling, use counter).
It seems this FTL was tailored with 16KiB eraesize in mind so to fit one
param block exactly, to have two copies of the partition table on two
blocks.
Later pxa27x devices have same size but 128KiB erasesize and less blocks
(56 vs. 448) but the same schema was adopted, even if the two tables are
now in the same eraseblock.
For the purpose of the MTD parser only the read part of the code was taken.
The NAND drivers that can use this parser are sharpsl.c and tmio_nand.c.

This makes TRX parsing code reusable with other platforms and parsers.
Please note this patch doesn't really change anything in the existing
code, just moves it. There is still some place for improvement (e.g.
working on non-hacky method of checking rootfs format) but it's not
really a subject of this change.
