common: Drop linux/printk.h from common header

This old patch was marked as deferred. Bring it back to life, to continue
towards the removal of common.h

Move this out of the common header and include it only where needed.

bios_emulator: Add an option to enable debugging

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.

This is a BIOS emulator, porting from SciTech for u-boot, mainly for
ATI video card BIOS. and can be used for x86 code emulation by some
modifications.
