Subject: iio: light: jsa1212: Select REGMAP_I2C

This patch adds missing 'select' statement for jsa1212 driver.
Without regmap_i2c, we get the following error when loading the module:
Unknown symbol devm_regmap_init_i2c.

Subject: iio: ak8975: fix AK09911 dependencies

ak8975 depends on I2C and GPIOLIB, so any symbols that selects
