sfc: Rework MAC, PHY and board event handling

Browse Source 
From: Steve Hodgson <shodgson@solarflare.com>

MAC, PHY and board events may be separately enabled and signalled.
Our current arrangement of chaining the polling functions can result
in events being missed.  Change them to be more independent.
