[PATCH] skge: make Genesis/Broadcom code work

Browse Source 
Rewrite the code for handling the Broadcom PHY to something that
works. Remove link polling because Broadcom and Yukon don't need it.
When I wrote initial code, didn't have a genesis chipset based
board to test, so it was a non-working guess.
