bnxt_en: log firmware debug notifications

Browse source 
[ Upstream commit a44daa8fcb ]

Firmware is capable of generating asynchronous debug notifications.
The event data is opaque to the driver and is simply logged. Debug
notifications can be enabled by turning on hardware status messages
using the ethtool msglvl interface.
