Subject: [PATCH] clk: renesas: r9a06g032: Avoid needless probe deferring

To avoid all SoC peripheral drivers deferring their probes, both clock and
pinctrl drivers should already be probed. Since the pinctrl driver requires
a clock to access the registers, the clock driver should be probed before
the pinctrl driver.

Therefore, move the clock driver from subsys_initcall to core_initcall.
