Hisilicon/D03/D05: Add AddressTranslationOffset support
Assign valid value to AddressTranslationOffset to support
address translation between domains of CPU and PCIe, which
is need by GOP to enable frame buffer.
This patch fix the bug:
Kernel (4.12, without the vga driver) boot hang with kernel panic
while kernel accesses UEFI GOP frame buffer.
