[PATCH v2 14/21] ARM: rpi: rpi3: disallow MMU_EARLY && 64BIT

[Ahmad Fatoum]

Early MMU setup in 64-bit Raspberry Pi 3 barebox hangs, while normal
setup concludes normally. Until this is figured out, disallow build
of 64-Bit Raspberry Pi 3 support while CONFIG_MMU_EARLY=y.

This issue doesn't affect the Raspberry Pi 4.
