arm64: dts: qcom: sa8295p-adp: disallow regulator mode switches

Browse Source 
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.
