regulator: twl-regulator: fix n_voltages for twl6030 variable LDOs
The n_voltages initializer for the TWL6030_ADJUSTABLE_LDO macro is
off by one, causing the the highest supported voltage to be
unreachable. Setting the machine constraints to only allow the
highest voltage causes errors:
machine_constraints_voltage: VAUX3_6030: unsupportable voltage constraints
twl_reg twl_reg.39: can't register VAUX3_6030, -22
twl_reg: probe of twl_reg.39 failed with error -22
This patch fixes the off by one error. Tested by setting
VAUX3_6030 to 3.3V.
