[ Upstream commit 369f772299821f93f872bf1b4d7d7ed2fc50243b ]
The pinctrl-rtd driver uses 'devm_regmap_init_mmio', which requires 'REGMAP_MMIO' to be enabled.
Without this selection, the build fails with an undefined reference: aarch64-none-linux-gnu-ld: drivers/pinctrl/realtek/pinctrl-rtd.o: in function rtd_pinctrl_probe': pinctrl-rtd.c:(.text+0x5a0): undefined reference to __devm_regmap_init_mmio_clk'
Fix this by selecting 'REGMAP_MMIO' in the Kconfig.
