0b56afadf3 make this idempotent. bus.h needs to include it, and other things which 
may include something that includes bus.h may include it as well.

6826c7bf48 bus memory and I/O space access functions/macros, to be used by 
machine-independent code for more sane access to bus resources.
New functions will be added to this set, in the future, as appropriate,
but this is a good starting set.  Defines:
	bus_{io,mem}_{map,unmap}
	bus_{io,mem}_{read,write}_{1,2,4,8}
functions, and several types to go with them.

18ec26aa21 add _MACHINE and _MACHINE_ARCH, which are like MACHINE and MACHINE_ARCH, 
execpt without quotes.  meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).
