net: pcs: xpcs: add specific vendor supoprt for Wangxun 10Gb NICs

Browse Source 
Since Wangxun 10Gb NICs require some special configuration on the IP of
Synopsys Designware XPCS, introduce dev_flag for different vendors. Read
OUI from device identifier registers, to detect Wangxun devices.

And xpcs_soft_reset() is skipped to avoid the reset of device identifier
registers.
