[PATCH] arm32: simplify ARM_MMU_KEEP usage

[Rolf Eike Beer]

All current users need to add a KEEP() around the argument so the value is
actually kept, which doesn't feel very natural and is prone to upcoming bugs as
the name suggests that this macro alone already keeps things. Move that directly
into the definition.

I'm unsure if ARM_MMU_DISCARD() needs the same treatment for the non-MMU case.
I suspect noone has tried dead code elimination for non-MMU?
