[ Upstream commit 2a6164cef63cae77edbd9deef844b1774886fcb7 ]
Do not allow the RPMh regulators to switch to low-power mode with an exception for the UFS regulators (l3c, l6c, l10c and l17c) 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.
