Verification of the kernel image (in old format) and finding kernel
data is moved to a dedicated routine. The routine will also hold
support for, to be added, new image format.

Move FDT blob finding and relocation to a dedicated
get_fdt() routine. It increases code readability and
will make adding support for new uImage format easier.

This patch moves common pre-boot allocation steps shared between PPC
and M68K to a helper routines:
common:
- get_boot_sp_limit()
- get_boot_cmline()
- get_boot_kbd()
platform:
- set_clocks_in_mhz()

Implementation of the do_bootm_linux() and other bootm helper routines is
architecture specific code. As such it resides in lib_<arch> directories
in files named <arch>_linux.c
This patch renames those files to a more clear and accurate
lib_<arch>/bootm.c form.
List of the renamed files:
lib_arm/armlinux.c -> lib_arm/bootm.c
lib_avr32/avr32_linux.c -> lib_avr32/bootm.c
lib_blackfin/bf533_linux.c -> lib_blackfin/bootm.c
lib_i386/i386_linux.c -> lib_i386/bootm.c
lib_m68k/m68k_linux.c -> lib_m68k/bootm.c
lib_microblaze/microblaze_linux.c -> lib_microblaze/bootm.c
lib_mips/mips_linux.c -> lib_mips/bootm.c
lib_nios/nios_linux.c -> lib_nios/bootm.c
lib_nios2/nios_linux.c -> lib_nios2/bootm.c
lib_ppc/ppc_linux.c -> lib_ppc/bootm.c
lib_sh/sh_linux.c -> lib_sh/bootm.c

Changes to match 5121 device tree going mainline in 2.6.25.
Change OF_SOC from "soc5121" to plain "soc".

The existing code assumes the SDRAM row refresh period should always
be 15.6 us. This is not always true, and indeed on the ATNGW100, the
refresh rate should really be 7.81 us.
Add a refresh_period member to struct sdram_info and initialize it
properly for both ATSTK1000 and ATNGW100. Out-of-tree boards will
panic() until the refresh_period member is updated properly.
Big thanks to Gerhard Berghofer for pointing out this issue.

The (now obsolete) atngw100 flash programming code was having problems

programming code may have the same bug, so import fix for this problem
from the AVR32 Linux BSP.

The default load address is SDRAM + 2MB, not SDRAM + 4MB. The latter
wouldn't have worked anyway since the board can only access 4MB of
SDRAM.

Many people run into problems when they compile a big kernel and load
the uImage at the default SDRAM + 2MB address as the kernel will
overwrite the uImage as it is being unpacked. Increase the default
load address so that we can load a 4MB kernel image without any
problems.
