[RFC] [PATCH v2 10/13] wifi: ath11k: bind to QRTR endpoint ID in ath11k_qmi_init_service

[Mihai Moldovan <ionic@ionic.de>]

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).

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-05266-QCAHSTSWPLZ_V2_TO_X86-1
