At present there are DEBUG options spread around the place. If you enable
one and not another you can end up with an emulator that does not work,
since each file can have a different view of what the registers look like.
To fix this, create a global CONFIG_X86EMU_DEBUG option that keeps
everything consistent.

As well as locating the ROM on the PCI bus, allow the ROM to be supplied to
the emulator. Split the init up a little so that callers can supply their
own interrupt routines. Also allow a vesa mode to be provided, to be
selected once the BIOS run is complete.

There is an implicit assumption that x86 machines want to use raw I/O in the
BIOS emulator, but this should be selectable. Add an CONFIG_X86EMU_RAW_IO
option to control it instead.
Also fix a few bugs which cause warnings on x86 and adjust the Makefile to
remove the assumption that only PowerPC uses the emulator.

This makes sure we have inline functions such as inb/outb that
are used in these two files by including the arch-specific
<asm/io.h> header. However the ARM version does not provide the
accessors unless the config symbol __io is also defined so add
that in front of the include.
After this the bios emulator will compile on ARM systems.
