soc/mediatek/mt8188: devapc: Update permission for master domain setup
Currently, all the masters controlled by DAPC are in domain 0. With this setting, there is a potential security problem. For example, if a certain master is somehow hacked, it may attempt to access registers that it is not supposed to, with successful results. This is due to the fact that, in the current setting, all masters are in domain 0 and can access almost all registers. To prevent this problem, we assign masters to different domains and restrict access to registers based on each domain. This patch updates the permission settings for domains 2, 3, 4, 5, 7, 8, 9, and 14, as these domains will be assigned masters in the upcoming patch.
