[PATCH v4 09/12] wifi: ath11k: bind to QRTR endpoint ID in ath11k_qmi_init_service

From: Mihai Moldovan <redacted>

If possible, fetch the QRTR endpoint ID in ath11k_qmi_init_service, just
before calling qmi_handle_init, and make it available in the qmi_handle.

qmi_helpers will then automatically bind to this endpoint for us.

This finally allows using multiple ath11k-based cards with the same QRTR
node/port combination to work simultanenous (and, for that matter, at
all).
