From: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx>

With the PMIC GLINK service, the host OS subscribes to USB-C altmode
messages, which are sent by the firmware to notify the host OS about
state updates and HPD interrupts.

The pmic_glink_altmode driver registers for these notifications and
propagates the notifications as typec_mux, typec_switch and DRM OOB
notifications as necessary to implement DisplayPort altmode support.
