Re: [PATCH v2 2/2] armv8: Disable SYS_DCACHE_OFF & SYS_ICACHE_OFF for ARM64

Ideally SYS_ICACHE_OFF and SYS_DCACHE_OFF should never be set for ARM64 (ARMv8) platforms, as it makes booting u-boot slower on these platforms.

However, if some platforms require ICACHE or DCACHE to be disabled only for the smaller SPL stage, we should support such configurations in u-boot as well.

Compile-tested for:

• qemu arm64
• imx8
• stm32

and run-tested on:

• Qualcomm RB3 platform
