As suggested by Tom, disable setting ICACHE and DCACHE off for ARM64
platforms. It is also noticed that with CACHEs off u-boot on ARM64 (ARMv8)
boots slower.

If some platforms still wish to turn off ICACHE / DCACHE during the
SPL stage, support that configuration as well.

While at it, also fix an compilation issue for stm32mp when 
SYS_DCACHE_OFF and/or SYS_DCACHE_SYS are enabled.
