Fallback on direct PCI access when no BIOS32 is available

Some hardware start shippping with no BIOS32 at all, and we'll have to
implement ACPI to get the address of the mmconfig table.  In the meanwhile,
we can hope that the direct probe works (it does on HP820 for instance).

* linux/src/arch/i386/kernel/bios32.c (pcibios_init): Also try
check_direct_pci() when bios32 probing failed.
