hw/arm/aspeed_ast27x0 Introduce vbootrom memory region

Browse source 
Introduce a new vbootrom memory region. The region is mapped at address
"0x00000000" and has a size of 128KB, identical to the SRAM region size.
This memory region is intended for loading a vbootrom image file as part of the
boot process.

The vbootrom registered in the SoC's address space using the ASPEED_DEV_VBOOTROM
index.
