staging: iio: isl29028: add runtime power management support

Browse source

This patch adds runtime power management support to the isl29028 driver.
It defaults to powering off the device after two seconds of inactivity.

isl29028_chip_init_and_power_on() currently only zeros the CONFIGURE
register on the chip, which will cause the chip to turn off. This patch
also renames that function to isl29028_clear_configure_reg() since it is
now used in several places.
