Subject: [PATCH v4 20/23] ARM: shmobile: rcar-gen2: Stop passing mode pins state to clock driver

Now the R-Car Gen2 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 call of_clk_init() instead.

v4:
  - Add Acked-by,
  - Rebase on top of "ARM: shmobile: rcar-gen2: Obtain extal frequency
    from DT",
  - Remove the call to rcar_gen2_read_mode_pins(),

v3:
  - Drop "select MFD_SYSCON", as the clock driver no longer uses syscon,

v2:
  - Kill compiler warning if CONFIG_ARM_ARCH_TIMER is not enabled.
