[ Upstream commit 31a95fe0851afbbc697b6be96c8a81a01d65aa5f ]
The QCM6490 is a variant of SC7280, with the usual set of protection
domains, and hence the need for a PD-mapper. In particular USB Type-C
port management and battery management is pmic_glink based.
Add an entry to the kernel, to avoid the need for userspace to provide
this service.
