It only fixes the redundant reset and overriding the smartidle-wakeup
OCP setting (done by hwmod) with the smartidle in the driver.
Doing this doesn't really break anything as yet in mainline, but will
cause timer wakeup issues once OFF mode is in place for OMAP4. On OMAP5
however this was causing more issues as the softreset bit position is
different than on OMAP2/3/4.
So it should be ok to queue this in for 3.4 considering neither OMAP4
OFF, not OMAP5 support is in mainline yet.
