[PATCHv3] arm: omap2: timer: always define omap4_local_timer_init

[Felipe Balbi]

omap4_local_timer_init() can be used by other
platforms as is. At least AM437x wants to use
it. Instead of making omap4-only and providing
a stub for builds without OMAP4, we can just
always define that function.

changes since v2:
  - move ifdefs around

changes since v1:
  - make sure result builds on AM43xx-only builds

OK -> the change was subtle for v3 -> you now have the entire
omap4_local_timer_init under the same #ifdef as for the rest.

but then, you are wrong on $subject and commit message since you are no
longer always enabling the local_timer_init.

otherwise the change itself looks ok to me.
