This moves the BCM63xx partition parser down into the
parser subdirectory. No functional change.

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.

Strings read from flash could be missing null termination characters, or
not contain valid integers.

Null terminate the strings and check for errors when converting them to
integers.

Also validate that the addresses are at least BCM963XX_EXTENDED_SIZE
because this will be subtracted from them.

Read nvram directly from flash instead of using the in-memory copy that
mach-bcm63xx has, to remove the dependency on mach-bcm63xx and allow the
parser to work on bmips too.

Rename remaining BCM63XX defines to BCM963XX as these are properties of
the flash layout on the board.

BCM963XX_DEFAULT_PSI_SIZE changes from SZ_64K to 64 because it will be
multiplied by SZ_1K later on.

Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for MIPS for 4.5 plus some 4.4 fixes.

  The executive summary:

   - ATH79 platform improvments, use DT bindings for the ATH79 USB PHY.
   - Avoid useless rebuilds for zboot.
   - jz4780: Add NEMC, BCH and NAND device tree nodes
   - Initial support for the MicroChip's DT platform.  As all the device
     drivers are missing this is still of limited use.
   - Some Loongson3 cleanups.
   - The unavoidable whitespace polishing.
   - Reduce clock skew when synchronizing the CPU cycle counters on CPU
     startup.
   - Add MIPS R6 fixes.
   - Lots of cleanups across arch/mips as fallout from KVM.
   - Lots of minor fixes and changes for IEEE 754-2008 support to the
     FPU emulator / fp-assist software.
   - Minor Ralink, BCM47xx and bcm963xx platform support improvments.
   - Support SMP on BCM63168"
