Remove unnecessary delay. I don't see any comments in data sheet
that requires 10ms delay after device reset. Because that code was
there from day 1, I guess it was added to give enough settlement
time after updating BGE_MAC_MODE register.
The recommended delay time for BGE_MAC_MODE after updating is 40us
and it was already done in r241219.
