[PATCH] arm: omap2: board-generic: use omap4_local_timer_init for AM437x

[Felipe Balbi]

AM437x-based boards, can use omap4_local_timer_init()
just fine. Let's use that instead.

This is breaking AM43x-epos board.

seems like the 32k timer isn't ticking. I don't have EPOS around, care
to confirm if that board has 32k oscillator populated ? If it doesn't,
then we should probably disable counter32k:
