21ab095cbc clk: renesas: r8a77980: Fix RPC-IF module clock's parent
Testing has shown that the RPC-IF module clock's parent is the RPCD2
clock, not the RPC one -- the RPC-IF register reads stall otherwise...

0a87bf6cd5 clk: renesas: r8a77980: Add CMT clocks
Now that RCLK has been added by Geert, we can add the CMT module clocks.

Based on the original (and large) patch by Vladimir Barinov.

3a251270e6 clk: renesas: r8a77980: Add OSC predivider configuration and clock
R-Car Gen3 Hardware Manual Rev.0.54 documents the relation between the
MD13 and MD14 mode pins, and the OSC EXTAL predivider, as used by the
OSC clock.  Hence augment the configuration structure with all
documented predivider values.

Add the OSC clock using the configured predivider.
