pmdomain: mediatek: Add support for RTFF Hardware in MT8196/MT6991

New generation SoCs use a new RTFF Hardware to save power during
operation of various IPs, other than managing isolation of the
internal buck converters during powerup/down of power domains.

Since some of the power domains need different RTFF handling, add
a new scpys_rtff_type enumeration and hold the value for each
power domain in struct scpsys_domain_data.

If RTFF HW is available, the RTFF additional power sequences are
handled in scpsys_ctl_pwrseq_{on,off}().
