[ Upstream commit 412737a60c846a6adb7f7571905c200da036815e ]
Do not allow the RPMh regulators to switch to low-power mode with an
exception for the UFS regulators (l7c and l3d) as UFS supports an idle
mode.
This specifically avoids having regulators be but in low-power mode when
only some consumers specify loads while the actual total load really
warrants high-power mode.
