We changed the timeout for the interrupt coealescing for
calibration, but that wasn't effective since we changed
that value back before loading the firmware. Since
calibrations are notification from firmware and not Rx
packets, this doesn't change anyway - the firmware will
fire an interrupt straight away regardless of the interrupt
coalescing value.
Also, a HW issue has been discovered in 7000 devices series.
The work around is to disable the new interrupt coalescing
timeout feature - do this by setting bit 31 in
CSR_INT_COALESCING.
This has been fixed in 7265 which means that we can't rely
on the device family and must have a hint in the iwl_cfg
structure.
