Subject: [PATCH v3 1/2] soc: qcom: pd-mapper: Add support for SA8775P

Add support for the Qualcomm SA8775P SoC to the protection
domain mapper. SA8775P share the same protection domain
configuration as SC8280XP with an additional gpdsp domain,
except for charger_pd.

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