[PATCH] PAL: Support of the fixed PHY

This makes it possible for HW PHY-less boards to utilize PAL goodies.  Generic
routines to connect to fixed PHY are provided, as well as ability to specify
software callback that fills up link, speed, etc.  information into PHY
descriptor (the latter feature not tested so far).
