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

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.

TEST=play video and see codec irq count is incrementing.
