ARM: shmobile: r8a7779: Stop passing mode pins state to clock driver

Now the R-Car H1 CPG clock driver obtains the state of the mode pins
from the R-Car RST driver, there's no longer a need to pass this state
explicitly. Hence we can just remove the .init_time() callback, the
generic ARM code will take care of calling of_clk_init() and
clocksource_probe().
