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. Fixes: 527c02f66d263d2e ("soc: renesas: Add R-Car RST driver") Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
