Interface change to expose idle restart/shutdown APIs for WLAN

issues among various branches of kernel and WLAN driver. The actual

For USB devices, irrecoverable scenarios in firmware
can lead to USB bus disconnect. In USB disconnect, the
interface and dev structures passed by USB sub system
are freed and are no longer valid. The current
implementation is PCIe specific and assumes dev struct
being present and valid always. The clean way to handle
this for HL(USB/SDIO) is to call pld_usb_remove in
disconnect and pld_usb_probe in re-connect after a recovery

cnss_usb_data structure member plat_priv remains uninitialized till
the function invoke of cnss_usb_probe. This leads to the access of
uninitialized pointer plat_priv if CLD gets loaded prior to
firmware download completion. Hence initialize the plat_priv
in cnss_usb_data structure during cnss_usb_init.

There may be a issue if save PCIe config space with bus master
enabled. During resume, since the bit will be restored first,
device will think master is ready and then trigger MSI for some
events, but actually MSI config has not been restored yet which
will mask the MSI. To avoid this, clear the bus master bit before
save config space and the bit will be enabled at a later time.
