This patch is added for PHY whose register offset value exceeds 0xFF and cannot be used with "unsigned char" datatype in miiphy_read, miiphy_write and miiphy_register functions. Datatype of register offset is changed to unsigned short instead of unsigned char so that offset value greater then 0xFF can be used.
