drm: renesas: shmobile: Rename input clocks

Prepare for DT bindings by using more appropriate names for the input
clocks.

Note that all LDDCKR_ICKSEL_* definitions but the one for the bus clock
are valid only for SH7724, so the clock selection code needs to be
updated when extending clock support to other SoCs.
