soc/mediatek/mt8188: Allow CPUfreq hardware to access MCUPM registers
This patch fixes AP hanging issue caused by the handshaking between
MCUPM and CPUfreq driver.
CPUfreq hardware failed to read MCUPM registers due to DEVAPC
permission. Therefore, update the DEVAPC settings to fix this issue.
BUG=none
TEST=CPUfreq in kernel test pass.
