ARM: uniphier: support Debug UART
For ARM32 architecture, CONFIG_DEBUG_LL is available for early
low-level debugging (and actually UniPhier 32bit SoCs use it), but
ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART
is available as an architecture-independent debug facility.
This commit supports it on all the UniPhier SoCs (including the new
ARMv8 SoCs), which is very useful for new SoC bringups.
