ARM: dts: sun8i-q8-common: Do not set constraints on dc1sw regulator
dc1sw is an on/off only regulator and as such it cannot have constraints.
This is a limitation of the kernel regulator implementation which resolves
supplies on the first regulator_get(), which is done after applying
constraints, and applying the constrains will fail because it calls
_regulator_get_voltage() and _regulator_do_set_voltage() both of which
will fail on a switch regulator when there is no supply (yet).
This causes registering of all axp22x regulators to fail with the
following errors:
[ 1.395249] vcc-lcd: failed to get the current voltage(-22)
[ 1.405131] axp20x-regulator axp20x-regulator: Failed to register dc1sw
[ 1.412436] axp20x-regulator: probe of axp20x-regulator failed with error -22
This commit removes the constrains on dc1sw / vcc-lcd fixing this problem
note that dcdc1 itself is contrained to the exact same values, so this
does not change anything.
