Voltage setting for BUCK7 and BUCK8 was not supported by s5m8767 driver.
If they were configured in DTS then the driver probing would fail with
EINVAL:
[ 0.288474] VCC_SUB_1.35V: failed to apply 1350000uV constraint
[ 0.288671] s5m8767-pmic s5m8767-pmic: regulator init failed for 35
[ 0.294931] s5m8767-pmic: probe of s5m8767-pmic failed with error -22
This patch adds support for BUCK7 and BUCK8 regulators using standard
regmap get/set voltage sel functions.

Since essentially all GPIO controlled regulators are voltage regulators
make the regulator-type property optional, defaulting to voltage.

The Ux500 platform has been converted to do device-tree only
boots, no longer supports platform data passing, so this
probe path is unused. Delete it, simplifying the driver a
whole lot.

Eliminate the gap between DT becoming available and this being used to say
we have full constraints by checking directly for DT every time we check
for full constraints. This improves interoperaton with optional regulator
support.

Commit "i2c: core: make it possible to match a pure device tree driver"
changed semantics of the i2c probing for device tree devices.
Device tree probed devices now get a NULL i2c_device_id pointer.
This causes the regulator name to be set to NULL and the regulator
registration to fail.

wm5110 provides different voltage configurations than the other Arizona
parts, this patch adds support for this into the regulator driver. Also

Commit c368e5fc2a "regulator: fixed:
get rid of {get|list}_voltage()" broke regulator_list_voltage() for
the fixed regulator, because an earlier commit
5a523605af "regulator: core: provide
fixed voltage in desc for single voltage rail" missed to add support
for the fixed-voltage special case to that function. This patch
fixes that regression.
