Add new CONFIG_CLK_RCAR to control compilation of shared code for R-Car
clock drivers (renesas-cpg-mssr.c). Enable this for R-Car Gen2 and 3.

This is necessary so that CONFIG_CLK_RENESAS can be enabled, allowing
recursion into the drivers/clk/reneasas directory, without bringing in
the R-Car support code. The support code contains platform specific
access (TMU_BASE) which is not needed on other Renesas devices such as
RZ/N1.

(no changes since v5)

Changes in v5:
- add symbol CONFIG_CLK_RCAR and select it for R-Car Gen2/3.
- use this to control compilation of renesas-cpg-mssr.c, rather
  than CONFIG_CLK_RENESAS which also controls directory recursion.
- update the commit message accordingly

Changes in v3:
- added tags
