Currently, the fdt_cpu_fixup() implementation assumes:
1. We have one CPU DT for each HART under /cpus DT node
2. The CPU DT nodes are named sequentially (i.e cpu@0,
cpu@1, ...) which is not true for discontinuous and
sparse HART ids (i.e. cpu@0, cpu@4, cpu@5). Generally,
CPU DT node are named based on HART id and not HART
index
If any of the above assumptions are violated then the
fdt_cpu_fixup() will not work.
This improves fdt_cpu_fixup() implementation and makes
it independent of above assumptions.

FDT helper file contain both fdt fixup and parsing functions.
Split the fixup related functions to a separate file for a better code
organization.
