Transmit arbiter timeouts happens when Gigabit sends to 100Mbit port
on same switch and pause occurs.

Cleanup messages (for debug) about PHY interrrupts, because when
user can't get driver working that is often the problem.
Use a consistent way of enabling interrupts by port.

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.

The inlines and macro's needed some cleanup's and fixes:
 * change name of macro SKGEMAC_REG to SK_REG to better reflect usage
   and fix comments
 * ditto for SK_GEXM_REG -> SK_XMAC_REG and SKGEGMA_REG -> SK_GMA_REG

 * change skge_gm_ to just gm_ since it is just a local function and long
   names look ugly.
 * change skge_xm_ to just xm_
 * fix xm_write32 to write as two u16's with correct byte order
 * fix xm_outaddr to correctly use offset
