Subject: [PATCH -next] iio: st_sensors: Fix build error

IIO_ST_SENSORS_CORE select IIO_ST_SENSORS_I2C
unconditionally, if REGMAP_I2C is not set, build fails

drivers/iio/common/st_sensors/st_sensors_i2c.o: In function `st_sensors_i2c_configure':
st_sensors_i2c.c:(.text+0x58): undefined reference to `__devm_regmap_init_i2c'

This patch selects REGMAP_I2C to fix it.
IIO_ST_SENSORS_SPI is similar to SPI issue.

Reported-by: Hulk Robot <hulkci@...wei.com>
Fixes: 062809ef7733 ("iio: make st_sensors drivers use regmap")
