[RFT 1/3] wifi: brcmfmac: support per-vendor cfg80211 callbacks and firmware events

[Arend van Spriel <arend.vanspriel@xxxxxxxxxxxx>]

Adding two vendor operations that can be used to provide per-vendor
cfg80211 callbacks and per-vendor handlers for firmware events. These
two are often related to handling interactions from user-space through
nl80211. Exporting brcmf_fweh_register() for registering the per-vendor
event handler callbacks. Some other exports for get event name string
and allowing use of brcmf_dbg() in per-vendor module.
