isl29028_chip_init_and_power_on() calls isl29028_set_proxim_sampling()
and this is not needed until the user actually needs to take a proximity
reading. This patch moves the isl29028_set_proxim_sampling() call from
isl29028_chip_init_and_power_on() to isl29028_enable_proximity().
This sets the stage for faster resume times from the runtime power
management if the user is only querying the ALS/IR sensor.
