Commit b1cbdb00d{OMAP: clockdomain: Wait for powerdomain to be ON
when using clockdomain force wakeup} was assuming that pwrdm_state_switch()
does wait for the powerdomain transition which is not the case.

Fix this API by adding the pwrdm_wait_transition().

Sounds like this fixes a major kernel oops bug for Tony so this should go 
in ASAP to v3.3-rc series.

Got a random oops with this one applied still, just happened
to take longer this time :(

Oh well.  Will queue it for v3.4-rc1 then...

It seems that I need this patch plus need to undo the wrong
serial muxing in commit 7496ba30 (ARM: OMAP2+: UART: Add default mux
for all uarts) to make my zoom3 boot reliably.

Regards,

Tony
