hw/pci/pcie: Do not set HPC flag if acpihp is used

Browse source 
Instead of changing the hot-plug type in _OSC register, do not
set the 'Hot-Plug Capable' flag. This way guest will choose ACPI
hot-plug if it is preferred and leave the option to use SHPC with
pcie-pci-bridge.

The ability to control hot-plug for each downstream port is retained,
while 'hotplug=off' on the port means all hot-plug types are disabled.
