Binbin Wu 2111fcffa5 hv: vtd: add config for bus limitation when init ...

Currently, hypervisor doesn't have the information of pci devices
on the platform when init. In order to reduce boot time and memory
usage, hypervisor set a bus limitation for pci devices when init vtd.
However, maximum bus number varies on different platforms.
This patch add a config for the bus limitation.
Set 0xF as the default value for the maximum bus number on sbl platform.
Set 0xFF as the default value for the maximum bus number on uefi platfrom.
