imx6: fix legacy IRQ support (4.19)
The PCIe DWC host controller is now using MSI
(Message-signaled-interrupts) by default.
While ath9k itself does support MSI here, a lot of wlan adapters do not.
Avoid non-functioning cards by simply continue to disable MSI for now.
This can be done by appending "pci=nomsi" to the boot cmdline.
Also an extra fix needs to be backported which avoids MSI initialization
which prevented legacy IRQ's init from taking over.
