arm64: dts: renesas: cat875: Add rx/tx delays

Browse Source 
[ Upstream commit e1a9faddffe7e555304dc2e3284c84fbee0679ee ]

The CAT875 sub board from Silicon Linux uses a Realtek PHY.

The phy driver commit bbc4d71d63549bcd003 ("net: phy: realtek: fix
rtl8211e rx/tx delay config") introduced NFS mount failures.  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
to the avb device node.
