PS8640 is a low power MIPI-to-eDP video format converter.
VRF12 does not provide power to PS8640 on krabby.
In original patch, VRF12 is not used, and is set to hardware control
for low power. We change the setting to remove hardware control.
Therefore, if we want to control VRF12 by software, we can control
it directly.

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 default permission.

We use parts of SRAM_L2C as the memory of PRERAM_CBMEM_CONSOLE before
DRAM calibration. When we check cbmem, we found the content of this
memory is unreadable.
The L3 (can be used as SRAM_L2C) is 1MB in total. However the BootROM
has configured only half of L2/L3 cache as SRAM. Therefore, decrease
the size of each SRAM region to fit into the first half of the cache.
