soc/mediatek/mt8188: Use MHz as unit for current_clk
The unit of current_clk in pmif_ulposc_check() should be MHz. We use
pmif_get_ulposc_freq_mhz() to get the default hardware value in MHz.
Without this modification, the judgement in pmif_ulposc_check() is
alway wrong due to the wrong unit.
TEST=build pass.
