PCI/ACPI: Fix bus range comparison in pci_mcfg_lookup()
The configuration data provided by an MCFG entry, i.e., PCI segment and bus
range, may span multiple host bridges.
pci_mcfg_lookup() previously required an exact match of the host bridge
starting bus and the MCFG starting bus, which made the following
configuration fail:
MCFG region:
segment: 0
bus range: 0x00-0xff
host bridge
segment: 0
bus range: 0x20-0x4f
Relax the bus range check in pci_mcfg_lookup() so we can use any MCFG entry
that contains the required bus range, as we do in pci_mmconfig_lookup().
