mt8173: Add support for new watchdog SMC
This patch adds support for a new SMC that can be used to control the
watchdog. This allows for a cleaner separation of responsibilities where
all watchdog operations have to go through Trusted Firmware and we could
no longer have kernel and firmware poking concurrently at the same
register block.
