ARM: arm32: fix realocate_to_curr_addr
...
After add aarch64 support (commit 868df08)
to realocation, MLO on beaglebone black do not boot any more.
The issue is, that addition of offset in one if-case was not done.
This patch fix this.

Rename our file_operations to cdev_operations which better matches

ARM: aarch64: Make early MMU support work
...
Until now it was not possible to enable the MMU in PBL because
create_section needs memory allocations which are not available. With
this patch we move the early MMU support to a separate file and all
necessary aux functions to mmu_64.h. create_sections is reimplmented
for the early case to only create 1st level pagetables.

ARM: Create own cache.c file for aarch64
...
cache.c does not work properly for aarch64. We create a struct cache_fns
using C preprocessor foo which assumes the existence of cache
maintenance operations with a certain name. These functions have other
names on aarch64. While we could fix this we do not need the automatic
cache function selection on aarch64 since here we only have one function
set.
Create a separate file and be done with this issue.
