sky2: receive FIFO checking
A driver writer from another operating system hinted that
the versions of Yukon 2 chip with rambuffer (EC and XL) have
a hardware bug that if the FIFO ever gets completely full it
will hang. Sounds like a classic ring full vs ring empty wrap around
bug.
As a workaround, use the existing watchdog timer to check for
ring full lockup.
