ARM: OMAP2+: clockdomain: add pwrdm_state_switch() call to clkdm_sleep()
In clkdm_sleep(), the powerdomain should be eligible to switch power
states right after the call to the low-level clockdomain sleep
function. We should have been tracking that with the
pwrdm_state_switch() code, but we weren't, for whatever reason. Fix that.
This resolves the "pwrdm state mismatch(cam_pwrdm) 3 != 0" that appears
during the OMAP4460 Pandaboard-ES PM test, e.g. here:
