pinctrl: microchip-sgpio: add missing select REGMAP_MMIO
The driver calls ocelot_regmap_from_resource() via <linux/mfd/ocelot.h>,
which internally uses devm_regmap_init_mmio() and requires REGMAP_MMIO.
The Kconfig entry does not select REGMAP_MMIO, causing a build failure
when no other driver in the config happens to pull in REGMAP_MMIO:
include/linux/mfd/ocelot.h:34:24: error: implicit declaration of function 'devm_regmap_init_mmio'
Found by randconfig testing on arm64; tinyconfig reproducer below.
Fixes: 2afbbab45c26 ("pinctrl: microchip-sgpio: update to support regmap")
