Platform,Silicon: use DxeRuntimeDebugLibSerialPort for runtime DXE drivers
Commit 4bf95a9f361e ("MdeModulePkg/ResetSystemRuntimeDxe: Add more
debug message") broke the DEBUG build for all platforms that rely on
MMIO mapped UART devices, since it introduces a DEBUG() print that
may trigger at runtime, at which such UART devices are usually not
mapped, resulting in an OS crash.
Given that this mostly only affects ARM and AARCH64, it is not unlikely
that similar inadvertent breakage will occur again in the future, so
let's fix this once and for all by switching affected platforms to the
new DxeRuntimeDebugLibSerialPort DebugLib implementation that takes care
not to touch the UART hardware after ExitBootServices().
