regulator: qcom-rpmh: extend to support multiple linear voltage ranges
Update rpmh_vreg_hw_data to support multiple linear voltage ranges for potential regulators which have discrete voltage program ranges. Suggested-by: David Collins <quic_collinsd@quicinc.com> Reviewed-by: David Collins <quic_collinsd@quicinc.com> Signed-off-by: Fenglin Wu <quic_fenglinw@quicinc.com> Link: https://msgid.link/r/20231214-pm8010-regulator-v2-1-82131df6b97b@quicinc.com Signed-off-by: Mark Brown <broonie@kernel.org>
