Vladimir Kondratiev 7c0acf868d wil6210: Tx performance monitoring
For performance monitoring, trace time intervals when Tx vring
is idle/not idle. Use CPU cycle counter for this, because jiffies is
too rough, and other precise time measurement methods involve
overhead while get_cycles() should be fast.
This used to provide some estimation for percentage when Tx vring
was idle, i.e. when hardware is under-utilized.
Estimation is not precise because of many reasons - CPU frequency scaling,
grt_cycles() may be per core etc. But still, it is good estimation

Vladimir Kondratiev a715c7ddd6 wil6210: improve debug for WMI receive
Print message if no events received. This should not happen.
If it is, it points to the problem in firmware.
Track also cases when multiple events processed in one IRQ

Print information as soon as possible - mbox pointers and
event header right after reading it. This helps to identify potential
problem with memory allocation for the event buffer.
