hw/pci-host/gpex: Define properties for MMIO ranges
ACPI DSDT generator needs information like ECAM range, PIO range, 32-bit
and 64-bit PCI MMIO range etc related to the PCI host bridge. Instead of
making these values machine specific, create properties for the GPEX
host bridge with default value 0. During initialization, the firmware
can initialize these properties with correct values for the platform.
This basically allows DSDT generator code independent of the machine
specific memory map accesses.
