Add pm8010 RPMH regulators for sm8550 boards

Merge series from Fenglin Wu <quic_fenglinw@quicinc.com>:

There are 2 PM8010 PMICs present in sm8550-mtp/sm8550-qrd boards and
each of them exposes 7 LDOs. Add RPMH regulator support for them.

Signed-off-by: Fenglin Wu <quic_fenglinw@quicinc.com>

Changes in v2:
- Updated subject prefix in the dt-binding commit and fixed the typo.
- Separate the DTS commit with board name prefixes.
- Link to v1: https://lore.kernel.org/r/20231211-pm8010-regulator-v1-0-571e05fb4ecc@quicinc.com
