The MediaTek MT8196 vlpckgen clock driver uses
__devm_regmap_init_mmio_clk() by devm_regmap_init_mmio(),
which is defined in drivers/base/regmap/regmap-mmio.c.
However, the driver's Kconfig entry does not select REGMAP_MMIO.
This causes a linker error when REGMAP_MMIO is not enabled.

Fix this by selecting REGMAP_MMIO in the Kconfig entry.
