Alistair Buxton 7c00692640 OMAP7XX: Rename all the rest of the omap730 references in omap1 core
This patch is part of a series which removes references to omap730 in code
which is shared with omap850, replacing them with references to omap7xx.

This updates all the remaining omap730 references in miscellaneous local
variables, macros and similar.
