Some code cleanliness issues found by Andrew Morton (thanks!)
which should not affect functionality, but which should
help make the code more maintainable.
In particular, we now:
* convert all #define's w/ a parameter to static inlines
* use 1UL rather than 1ULL when calculating an unsigned long
* use pci_disable_device
The resulting code is tested and seems to work fine...

This follow-on cleanup patch fixes the following
compiler warnings found by Andrew Morton:
drivers/edac/i5100_edac.c:258: warning: function declaration isn't a prototype
drivers/edac/i5100_edac.c:263: warning: function declaration isn't a prototype

drivers/edac/i5100_edac.c:372: warning: left shift count >= width of type
The i5100_ctl_page_to_phys was not used, it will be
re-added when the controller -> cpu address space
translations work.
