soc/mediatek/mt8196: Delay 0.5ms after enabling PMIF SPMI SW interface

The initialization process of SPMI requires a certain amount of time
(0.5ms) to ensure all components are correctly configured and
synchronized. Otherwise, if the SPMI calibration fails, it will result
in the non-serial firmware failing to boot.

TEST=Build pass, non-serial firmware boot ok.
BUG=b:341054056
