Same as r333305, with Linux 4.17 dts the compatible for the prcm added 'simplebus', it mean that the simplebus driver will attach to it at the BUS_PASS_BUS pass. Change the pass for the prcm driver to be at BUS_PASS_BUS so we will win the attach. This introduce a problem as this driver needs the omap_scm one to be already attached. omap_scm also attach at BUS_PASS_BUS but after the prcm one as it is after in the dtb and the simplebus driver simpy walk the tree to attach it's children. Use the bus_new_pass method to defer the frequencies read at BUS_PASS_TIMER. This fixes booting on pandaboard Approved by: re (rgrimes)
