Replace all relocate_code routines from ARM start.S files
with a single instance in file arch/arm/lib/relocate.S.
For PXA, this requires moving the dcache unlocking code
from within relocate_code into c_runtime_cpu_setup.

When adjusting peripheral clocks always use find_best_divider()
instead of clk_get_divider() even when a secondary divider is not
available. In the case where is requested clock is too slow to be
derived from the parent clock this allows a best effort to get close
to the requested clock.
This comes up for commands like "sf" where the user can pass a clock
speed on the command line or "sspi" where the clock is hardcoded to
1MHz, but the Tegra114 SPI controller can't go that low.

Boot ROM code creates TLB entries for 3.5G space before entering

to invalidate all these entries before relocation of u-boot code.
So this code to delete TLB entries after CPU initialization
is no longer required.

To align with chassis generation 2 spec, all cores are numbered in sequence.
The cores may reside across multiple clusters. Each cluster has zero to four
cores. The first available core is numbered as core 0. The second available
core is numbered as core 1 and so on.
Core clocks are generated by each clusters. To identify the cluster of each
core, topology registers are examined.
Cluster clock registers are reorganized to be easily indexed.

Sparc only really sets up the ramdisk, but we should still use
image_setup_linux() so that setup is common across all architectures
that use the FDT.
Cover-letter
Introduce a common image_setup_linux() function
This series continues the work to tidy up the image code. Each
architecture has its own code for setting up ready for booting linux.
An attempt is made here to unify these in a single image_setup_linux()
function.
The part of the image code that deals with FDT is split into image-fdt.c
and a few tweaks are added to make FIT images more viable in SPL.
