APU has its own device apc for control access by domains.
For Domain 0, the access to the following slaves are restricted to
security read and write:
apusys_ao-2, apusys_ao-4, apusys_ao-5, apu_sctrl_reviser,
apu_iommu0_r1 apu_iommu0_r2, apu_iommu0_r3, apu_iommu0_r4
apu_iommu1_r1, apu_iommu1_r2, apu_iommu1_r3,apu_iommu1_r4
For VPU, D0/D5 are set as no protection, other domains are forbidden.
For other slaves, the D0 is no protection, other domains are forbidden.

Add basic devapc (device access permission control) drivers.
DAPC driver is used to set up bus fabric security and data protection
among hardwares. DAPC driver groups the master hardwares into different
domains and gives secure and non-secure property. The slave hardware can
configure different access permissions for different domains via DAPC
driver.
1. Initialize devapc.
2. Set master domain and secure side band.
3. Set domain remap.
4. Set default permission.

eint event mask register is used to mask eint wakeup source.
All wakeup sources are masked by default. Since most MediaTek SoCs do
not have this design, we can't modify the kernel eint upstream driver to
solve the issue 'Can't wake using power button (cros_ec) or touchpad'.
So we add a driver here to unmask all wakeup sources.
