This reverts commit a8172c329f.
In the aforementioned patch, we allowed MCUPM to access secure
registers and set the domain to DOMAIN_2.
Additional attribute settings are also required when a hardware is
set to a specific domain. Otherwise, there would be violation between
hardware. Since MT8188 is in bring-up stage, we simply enable access
register permission for the DOMAIN_0 by default. So remove the wrong
setting for MCUPM, SCP and SSPM.
We will complete DEVAPC setting when the settings are confirmed.

When CONFIG_DEBUG_SMI is enabled SMM handler performs console hardware

Tested=On not public yet system, after exiting smm, uart console can
still work well.
