[DONOTMERGE] [NOTEVENRFC] [PATCH 02/11] net: qrtr: mhi: pass endpoint ID to MHI device on init

[Mihai Moldovan <ionic@ionic.de>]

This is the simple QRTR part of the ugly endpoint ID "IPC" hack.

On initialization, which is currently only implemented for the MHI
backend, the endpoint ID is written to the MHI device's MHI controller.
