micrel phy driver - updated(1) 



Hello all:

This patch fixes what Ben mentioned, namely duplicated ids.

From: David J. Choi <david.choi@micrel.com>

Body of the explanation: This patch has changes as followings;
 -support the interrupt from phy devices from Micrel Inc.
 -support more phy devices, ks8737, ks8721, ks8041, ks8051 from Micrel.
 -remove vsc8201 because this device was used only internal test at Micrel.
