regulator: ad5398: Add device tree support

Browse Source 
[ Upstream commit 5a6a461079decea452fdcae955bccecf92e07e97 ]

Previously, the ad5398 driver used only platform_data, which is
deprecated in favour of device tree. This caused the AD5398 to fail to
probe as it could not load its init_data. If the AD5398 has a device
tree node, pull the init_data from there using
of_get_regulator_init_data.
