[PATCH] pmdomain: mediatek: scpsys: add MT7629 support

[Chuanhong Guo]

MT7629 currently uses the MT7622 domain table through the device tree
fallback compatible. Attempting to power on the WB domain triggers a
warning during boot, and powering off AUDSYS times out.

Add an MT7629-specific match entry to register only ETHSYS, HIF0 and
HIF1, matching the domains exposed by the vendor driver. These occupy
the first three entries in the MT7622 domain table.
