hwmod look ups should no longer directly happen for dmtimer users of
DT-boot platforms. We separate out the code for platforms that are
still non-DT. Ultimately this code should be deleted if all platforms
are converted to DT-boot.
We use omap_dmtimer_powerup introduced earlier in the series to abstract
out the hwmod dependency for the same. This will help us move the generic
DT specific code out into drivers/clocksource/ later.
