soc/mediatek/mt8188: devapc: Allow APU to access BND_NORTH_APB2_S
Update BND_NORTH_APB2_S's domain 5 permission to allow the access from
APU. The APU requires certain information saved in BND_NORTH_APB2_S for
voltage tuning. If this information cannot be retrieved, the APU may
operate at a high frequency with low voltage. Consequently, the APU may
not function as expected.
