[PATCH 4/8] iio: frequency: admv4420: add missing select REMAP_SPI in Kconfig

[Javier Carrasco <javier.carrasco.cruz@gmail.com>]

This driver makes use of regmap_spi, but does not select the required
module.
Add the missing 'select REGMAP_SPI'.

Fixes: b59c04155901 ("iio: frequency: admv4420.c: Add support for ADMV4420")
