Removed the ppc bit operation functions and definitions in the ppc
file asm/bitops.h since these are already defined in the asm-generic header
files. Moved ffs64 definition to the mpc85xx header files because
the function requires the inclusion of linux/log2.h which also includes
asm/bitops.h.

The conflict was noted when UBIFS was enabled in barebox.

TLB support for the 85xx CPUs has been upgraded to support the MMUv2
page size definitions. This has been imported from U-Boot version
git-9407c3fc. This allows for future CPUs to make use of the new MMU
support.

Also the definition of MAX_MEM_MAPPED has been changed to avoid type
casting with "min" macro.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.
