[PATCH] gpio: xra1403: select REGMAP_SPI

[Arnd Bergmann <arnd@xxxxxxxx>]

Without the regmap code, we get a link error:

drivers/gpio/built-in.o: In function `xra1403_probe':
(.text+0x132e0): undefined reference to `__devm_regmap_init_spi'

Fixes: 5704520d7880 ("gpio: xra1403: Add EXAR XRA1403 SPI GPIO expander driver")
