hw/acpi/ich9: Add compat prop to keep HPC bit set for 6.1 machine type
To solve issues [1-2] the Hot Plug Capable bit in PCIe Slots will be
turned on, while the switch to ACPI Hot-plug will be done in the
DSDT table.
Introducing 'x-keep-native-hpc' property disables the HPC bit only
in 6.1 and as a result keeps the forced 'reserve-io' on
pcie-root-ports in 6.1 too.
