[PATCH] disable 1000Mb/s autonegotiation Marvell PHY for DM365/8processors

[Brilliantov Kirill Vladimirovich]

Hello!
Davinci DM365/8 processors have only 100Mb/s EMAC, I need disable 
1000Mb/s autonegotiation.
Tested on linux-2.6.18_pro500, Marvell 88E1111, TexasInstruments Davinci 
DM368ZCEF and TexasInstruments TMS320DM365ZCE30 processors.

Thank you and excuse me for my bad english.
