858290178f ppc: Enable full relocation to RAM
The following changes allow U-Boot to fully relocate from flash to
RAM:
 - Remove linker scripts' .fixup sections from the .text section
 - Add -mrelocatable to PLATFORM_RELFLAGS for all boards
 - Define CONFIG_RELOC_FIXUP_WORKS for all boards

Previously, U-Boot would partially relocate, but statically initialized
pointers needed to be manually relocated.

202d94875c ppc/85xx: Fix LCRR_CLKDIV defines
For some reason the CLKDIV field varies between SoC in how it interprets
the bit values.

All 83xx and early (e500v1) PQ3 devices support:
 clk/2: CLKDIV = 2
 clk/4: CLKDIV = 4
 clk/8: CLKDIV = 8

Newer PQ3 (e500v2) and MPC86xx support:
 clk/4: CLKDIV = 2
 clk/8: CLKDIV = 4
 clk/16: CLKDIV = 8

Ensure that the MPC86xx and MPC85xx still get the same behavior and make
the defines reflect their logical view (not the value of the field).

0e870980a6 8xxx: Removed CONFIG_NUM_CPUS from 85xx/86xx
The number of CPUs are getting detected dynamically by checking the
processor SVR value.  Also removed CONFIG_NUM_CPUS references from all
the platforms with 85xx/86xx processors.

This can help to use the same u-boot image across the platforms.

Also revamped and corrected few Freescale Copyright messages.

39121c0896 xes: Increase CONFIG_SYS_BOOTM_LEN to 16MB
Increasing CONFIG_SYS_BOOTM_LEN from 8 MB to 16 MB is necessary to
support uncompressing images larger than 8 MB when using the bootm
command.

Note that recent Linux kernels for the 85xx and 86xx map greater than
16MB of memory on bootup, but we use 16MB to maintain compatibility with
older Linux kernels for now.
