ppc: mpc85xx: fix memory size calculation ...

Fix the chip select configuration register offset increment and summing
of bank size so that, for chip select index greater than 0, barebox can
determine the total memory size from enabled banks.

ppc: remove bit operation headers file conflict ...

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

Also the definition of MAX_MEM_MAPPED has been changed to avoid type

The common bootm code used to load uImage contents to SDRAM

ppc: bootm: relocate fdt to valid boot memory ...

For the MPC85xx family of SOCs Linux expects any boot firmware
information to be passed in the first 64MiB of memory. This adds support
to ensure that the device tree is relocated to a valid location if it is
outside that address range.

For the other SOC family currently present in the ppc architecture, the
default is not to relocate as at Linux startup the virtual address
equals the physical address.
