wpaul 40da8227d3 Fix support for the PNIC II. Earlier I had assumed that the PNIC II was 
similar to the PNIC I (supported by the pn driver). In fact, it's really
a Macronix 98715A with wake on LAN support added. According to LinkSys,
the PNIC II was jointly developed by Lite-On and Macronis. I get the
feeling Macronix did most of the work. (The datasheet has the Macronix
logo on it, and is in fact nearly identical to the 98715 datasheet, except
for the extra wake on LAN registers.) In any case, the PNIC II works just
fine with the Macronix driver.

The changes are:

- Move PCI ID for the PNIC II from the pn driver to the mx driver.
- Mention PNIC II support in mx.4.
- Mention PNIC II support in RELNOTES.TXT and HARDWARE.TXT.
