Xi Chen 95d3c46a2f mediatek: mt8183: protect 4GB~8GB dram memory ...

The offset there is the virtual address space on the bus side (1-9GB for 8GB RAM),
and that emi_mpu_set_region_protection will translate to the physical memory space (0-8GB).

8GB is 33-bit (the memory bus width is 33-bit on this platform),
so 0x23FFFFFFFUL-EMI_PHY_OFFSET = 0x1_FFFF_FFFF.
