soc: ti: pm33xx: Fix some resource leak in the error handling paths of the probe function
[ Upstream commit 17ad4662595ea0c4fd7496b664523ef632e63349 ]
'am33xx_pm_rtc_setup()' allocates some resources that must be freed on the
error. Commit 2152fbbd47c0 ("soc: ti: pm33xx: Simplify RTC usage to prepare
to drop platform data") has introduced the use of these resources but has
only updated the remove function.
Fix the error handling path of the probe function now.
