soc: mediatek: pm-domains: Add wakeup capacity support in power domain

BugLink: https://bugs.launchpad.net/bugs/1969110
[ Upstream commit ac0ca395543af061f7ad77afcda0afb323d82468 ]

Due to some power domain needs to keep on for wakeup in system suspend,
so add GENPD_FLAG_ACTIVE_WAKEUP support in Mediatek power domain driver.
