fix(mt8186-emi-mpu): fix SCP permission

Browse source 
Hardware video decoding is not working after enabling EMI MPU protection
for SCP.

According to coreboot DEVAPC setting, SCP belongs to domain 4 instead of
domain 3. So correct the permission setting.

BUG=b:249954378
TEST=play video and see codec irq count is incrementing.
