Subject: [PATCH 2/2] ARM: omap: remove unused cpu detection macros

Now that OMAP730 and OMAP850 support is mostly unified, there's no
need for separate cpu detection macros for these architectures. At
least, currently there isn't, because both macros are unused.
cpu_is_7xx() seems to cover all possible uses.

0) Entirely untested!

1) And now the IS_OMAP_TYPE() macro "calls" for 730 and 850 are unused.
Not sure whether they should be removed too.

2) Note that cpu_is_omap343x(), cpu_is_omap447x(), and cpu_is_omap2423()
are all unused too. Reserved for future use, I guess.
