soc: renesas: Provide dummy rcar_rst_read_mode_pins() for compile-testing
If the R-Car RST driver is not included, compile-testing R-Car clock
drivers fails with a link error:
undefined reference to `rcar_rst_read_mode_pins'
To fix this, provide a dummy version. Use the exact same test logic as
in drivers/soc/renesas/Makefile, as there is no Kconfig symbol (yet) to
control compilation of the R-Car RST driver.
