Minor tweaks in the names to match the chips more closely.

Minor DLINK DL100xx support tweaks:

The DIROUT bit difference between the 19 and 22 is annoying. We can
set both bits on both parts without ill effect. Use this trick to
simplify the code.

The DELAYS in the MII bus bit-bang code for the DL100xx parts aren't
needed. Eliminate them.

MFp4:
o Add support for Tamarack TC5299J + MII found on SMC 8041TX V.2
and corega PCCCCTXD
o Add support for ISA/PCI RTL80[12]9 chips
o Improve support for the ax88790 based
o minor code movement
