Subject: [PATCH v1] soc: qcom: pd-mapper: Add support for SA8775P and QCS8300

Add support for the Qualcomm SA8775P and QCS8300 SoC to the
protection domain mapper. SA8775P and QCS8300 shares the same
protection domain configuration as SM8550, except charger_pd and
mpss_pd.

Add an entry to the kernel, to avoid the need for userspace to provide
this service.
