[PATCHv2 8/8] arm: omap3: prevent per_clkdm from attempting manual domain transitions

Attempting this will cause problems especially with off-mode enabled.
Previously this issue was hidden by the fact that per_clkdm never
attempted manual idle by software, as the usecounts for the clockdomain
were broken.
