clk: ti: am33xx: fix RTC clock parent
Right now, trying to use RTC purely with the ti-sysc / clkctrl framework fails to enable the RTC module properly. Based on experimentation, this appears to be because RTC is sourced from the clkdiv32k optional clock. TRM is not very clear on this topic, but fix the RTC to use the proper source clock nevertheless.
