acrn-config: remap PCI vbar address to high memory
1. If the device configure space is not fixed by ACPI and its pbar address is above 4G or lower than 2G, then remap the vbar address to high memory. 2. Due to GPU might have huge MMIO space which would result in HV_RAM_SIZE overflow, skip its vBAR remapping for now when the size high than 1GB.
