Minor updates for the ASIX AX88141, which is a newer version of the

Browse source 
AX88140A with power management and magic packet support. Correct the
addresses of the PCI power management registers and add some code to
detect the revision ID of the AX88141 and identify it in the probe
messages.

No other changes are needed since the AX88141 is functionally
identical to the AX88140A.
