Subject: [PATCH v4 18/23] ARM: shmobile: r8a7778: Stop passing mode pins state to clock driver

Now the R-Car M1A 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().
