This migrates isp1704 driver from old GPIO API to new descriptor
based GPIO API and drops useless platform data as a side-effect.
Migration is simple, since all mainline users are DT based and
DT API does not change. Out of tree users of the platform data
need to migrate to gpiod_lookup_table as described here:

This patch introduces device tree support to the isp1704 charger driver.
Adding support involved moving the handling of the enable GPIO from board
code into the driver.

The ISP1704/1707 chip can be put to full power down
state by asserting the CHIP_SEL line. This patch enables
platform or board specific hooks to put the device into
power down mode in case not needed.
This patch is a preparation for enabling this powering
routine in n900 (rx-51) devices.
Thanks to Heikki Krogerus for helping out with the patch.
