Allow CONFIG_CLK_RENESAS to be set without bringing in RCAR-GEN2/3 code.

CONFIG_RENESAS is used in drivers/clk/Makefile to control recursion into
the drivers/clk/renesas subdirectory. It also controls compilation of
renesas-cpg-mssr.c support code for the RCAR-GEN2 and RCAR-GEN3 devices.

The support code contains platform specific hardware access (TMU_BASE),
and it is not needed for other Renesas devices such as RZ/N1. Therefore,
alter Makefile to build renesas-cpg-mssr.c only for RCAR-GEN2 and RCAR-GEN3.
