[PATCH] Revert "ARM: AM33xx: fix module_wait_ready without clkctrl register"

[Dave Gerlach]

This reverts commit 183e2077d007aa4b697efba095ecfea7244a6107.

The original patch added a check to am33xx_cm_wait_module_ready for a
clkctrl offset of 0 as an invalid case, however, clkctrl offset of 0 is
perfectly valid for hwmods, in particular the rtc.

Without reverting this patch sometimes external aborts are seen on
am335x during boot. This is due to the am33xx_cm_wait_module_ready
function immediately returning 0 rather than waiting for the RTC_CLKCTRL
register to indicate it is actually ready before rtc register accesses
happen.
