Subject: [PATCH v2 2/4] dt-bindings: rpmh-regulator: Update pmic-id
 property description

The `pmic-id` property previously accepted a single lowercase alphabet
in the range [a-n]. However, on new targets such as Glymur, the
property uses a new format: `[A-N]_E[0-3]`, where `[A-N]` represents
the PMIC ID and `[0-3]` represents the BUS ID.

Update the property description to reflect this new pattern format,
matching the updated driver implementation.

Note - Old format [a-n] is still valid and will work for existing
targets.
