gpio: qixis: select CONFIG_REGMAP_MMIO

The regmap drivers need to be selected by each user, without that there
can be configurations that fail to link:

x86_64-linux-ld: drivers/gpio/gpio-qixis-fpga.o: in function `qixis_cpld_gpio_probe':
gpio-qixis-fpga.c:(.text+0x13a): undefined reference to `__devm_regmap_init_mmio_clk'
