The CAT875 sub board from Silicon Linux uses Realtek PHY.
The phy driver commit bbc4d71d63549bcd003
("net: phy: realtek: fix rtl8211e rx/tx delay config") introduced
NFS mount failure. Now it needs both rx/tx delays for the NFS mount to
work.
This patch fixes the NFS mount failure issue by adding "rgmii-id" mode
on the avb device node.
