For RPMH regulators it doesn't make sense to indicate
regulator-allow-set-load without saying what modes you can switch to,
so be sure to indicate a dependency on regulator-allowed-modes.

With this in place devicetree validation can catch issues like this:

    /mnt/extrassd/git/linux-next/arch/arm64/boot/dts/qcom/sm8350-hdk.dtb: pm8350-rpmh-regulators: ldo5: 'regulator-allowed-modes' is a dependency of 'regulator-allow-set-load'
            From schema: /mnt/extrassd/git/linux-next/Documentation/devicetree/bindings/regulator/qcom,rpmh-regulator.yaml

v1: https://lore.kernel.org/linux-arm-msm/20220902185148.635292-1-ahalaney@redhat.com/
Changes since v1:
  - Dropped first two patches in the series as they were user error
    (thanks Krzysztof for highlighting this!)
  - No change in the remaining patch

Krzysztof also asked if this patch in particular should apply to other
regulators, which I think it should for those regulator's who implement
set_mode(). Unfortunately I don't know of a good way to get that
information in order to apply it at a broader scope for devicetree
regulator validation. At least with this in place RPMH users can get
better coverage... if someone has suggestions for how to broaden the
scope I'm all ears!

Thanks,
Andrew
