[undi] Try matching UNDI ROMs in BIOS enumeration order
When searching for an UNDI ROM to match against a PCI device, search
in order of increasing ROM address (within the 128kB BIOS option ROM
area). This is likely (though not guaranteed) to match the order of
the original enumeration performed by the BIOS, which is in turn
likely to match the order of enumeration on the PCI bus.
Since we load at most one UNDI ROM, the net result is that we increase
our chances of loading the ROM corresponding to the selected PCI
device (rather than loading a ROM corresponding to a higher-numbered
PCI device with the same vendor and device IDs.)

[undi] Clean up driver and device name information
Fix the <NULL> driver name reported by "ifstat" when using the undipci
driver (due to the unnecessary extra device node inserted as a child
of the PCI device).
Remove the "UNDI-" prefix from device names since the driver name is
also now visible via "ifstat", and tidy up the device name to match
the format used by standard PCI devices.
The output from "ifstat" now resembles:
iPXE> ifstat
net0: 52:54:00:12:34:56 using undipci on 0000:00:03.0
iPXE> ifstat
net0: 52:54:00:12:34:56 using undionly on 0000:00:03.0

[undi] Allocate base memory before calling UNDI loader entry point
Allocate base memory (by decreasing the free base memory counter)
before calling the UNDI loader entry point, to minimise surprises for
the UNDI loader code.

Move most arch/i386 files to arch/x86, and adjust the contents of the
Makefiles and the include/bits/*.h headers to reflect the new
locations.
This patch makes no substantive code changes, as can be seen using a
rename-aware diff (e.g. "git show -M5").
This patch does not make the pcbios platform functional for x86_64; it
merely allows it to compile without errors.
