Currently, the cnss2 platform driver just can support one wlan device attached, so do the following changes to cover dual wlan card attach case. Firstly, delay the second device go to pcie link suspend and power off state to make sure it really finished the pcie enumeration. Then pcie enumeration succeeds with multi-devices. Secondly, supporting to write the qrtr node instance id to PCIE register for wlan fw reading, which can fix qmi message exchange failure if active two Hastings devices. Thirdly, change the usage of plat_env to support dual Hastings. Change-Id: Ica41a23d4e983b91c0ff1b4e76b380803fb877ab

CNSS2 platform driver uses QMI framework to communicate with WLAN

firmware. It sends and receives boot handshake messages to WLAN

firmware, which includes hardware and software capabilities and

configurations. It also sends WLAN on/off control message to

Using asynchronous probe will allow CNSS platform driver to

The features enable cld wlan driver to suspend pcie bus when APPS

The Feature uses runtime power management framework from kernel to

This config flag controls the feature per target based. The feature
