wil6210: fix device ready detection
Adjust driver behavior during FW boot. Proper sequence of
events after reset and FW download, is as following:
- FW prepares mailbox structure and reports IRQ "FW_READY"
- driver caches mailbox registers, marks mailbox readiness
- FW sends WMI_FW_READY event, ignore it
- FW sends WMI_READY event with some data
- driver stores relevant data marks FW is operational
