Subject: [PATCH v2] soc: qcom: pd-mapper: Add support for SA8775P and QCS8300

Add support for the Qualcomm SA8775P and QCS8300 SoCs to the
protection domain mapper. SA8775P and QCS8300 share the same
protection domain configuration as SM8550 with an additional
gpdsp domain, except for charger_pd and mpss_pd.

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