soc/mediatek/mt8192: mt6315: update initial flow
We saw EXT_PMIC_EN1 and PPVAR_DVDD_PROC_BC power off sequence
failure, and after checking MT6315 MT6315 PMIC protection key
summary.xlsx and MT6315 Top and CLK programming guide.docx,
we found there are something wrong about the sequence of magic
key protection flow and clk setting. Update correct initial
flow.
BUG=b:179000151
BRANCH=none
TEST=boot asurada correctly
