clk: mediatek: mt7981-topckgen: flag SGM_REG_SEL as critical
[ Upstream commit aa690050c00a251ab69e3c5204d582833d0b958c ] Without the SGM_REG_SEL clock enabled the cpu freezes if trying to access registers used by MT7981 clock drivers itself. Mark SGM_REG_SEL as critical to make sure it is always enabled to prevent freezes on boot even if the Ethernet driver which prepares and enables the clock is not loaded or probed at a later point.
