PNP: increase the maximum number of resources
On some systems the number of resources(IO,MEM) returnedy by PNP device is
greater than the PNP constant, for example motherboard devices. It brings
that some resources can't be reserved and resource confilicts. This will
cause PCI resources are assigned wrongly in some systems, and cause hang.
This is a regression since we deleted ACPI motherboard driver and use PNP
system driver.
