Skge driver was bringing link up/down when changing mac
address. This doesn't work in the bonding environment, and is
more effort than needed.

This is one of those workarounds sucked over from sk98lin driver.
The skge driver needs to detect the Yukon-Lite A0 chip properly,
and turn of Rx FIFO Flush.

Merge of four previous patches and the Kconfig fix
* Remove debug printk's
* whitespace cleanup and version number change
* clear interrupts, reset phy, and reset hardware on shutdown
* ignore 64bit counter overflow interrupts
* fix a couple of places where second port could clobber state
of first port.

Both revisions share the same PCI device ID and vendor ID but revision 2
of the device uses SysKonnect's chipset whereas revision 3 of the device
uses Realtek's 8169 chipset.
Credit goes to Christiaan Lutzer <mythtv.lutzer@gmail.com> for reporting
the issue and giving the actual value for the different revisions.

Some versions of the Marvell yukon generate bogus sensor warning interrupts.
The driver would flood log with these messages. Handle this situation
cleanly by masking away at boot time.

Rewrite the code for handling the Broadcom PHY to something that

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
