[v2,0/3] common/board_f: Make reserve_mmu generic

Changes in v2:
- split the original patch in 3 parts
- add function comments
- drop #ifdefs around asm/cache.h includes
- drop reserve_mmu function and leave only arch_reserve_mmu

For the following suggestion:
"Can you please try to use if() instead of #if as much as possible?"

I tried replacing in reserve_mmu
#if !(CONFIG_IS_ENABLED(SYS_ICACHE_OFF) && CONFIG_IS_ENABLED(SYS_DCACHE_OFF))
with
if (!(CONFIG_IS_ENABLED(SYS_ICACHE_OFF) && CONFIG_IS_ENABLED(SYS_DCACHE_OFF))) {
...
}
but it caused compile issues on different arm platforms such as:
...
arch/arm/lib/cache.c: In function 'arm_reserve_mmu':
arch/arm/lib/cache.c:134:11: error: 'volatile struct arch_global_data' has no member named 'tlb_size'
