Subject: regulator: qcom_smd: Fix voltage ranges for pm8x41

From: Stephen Boyd <[email protected]>

commit 290284776bb281759b11faa287b8abccaf74bfcb upstream.

The voltage ranges listed here are wrong. The correct ranges can be seen in the "native" spmi regulator driver qcom_spmi-regulator.c at pldo_ranges[], ftsmps_ranges[] and boost_ranges[] for the pldo, ftsmps, and boost type regulators. Port these ranges over to the RPM SMD regulator driver so that we list the appropriate set of supported voltages on pldos.

Doing this allows us to specify a voltage like 3075000 for l24, whereas before that wasn't a supported voltage.

Fixes da65e367b67e ("regulator: Regulator driver for the Qualcomm RPM")
