Subject: [PATCH] Revert "net: cadence: macb: sama7g5_emac: Remove USARIO CLKEN flag"

From: Ryan Wanner <Ryan.Wanner@...rochip.com>

This reverts commit db400061b5e7cc55f9b4dd15443e9838964119ea.

This commit can cause a Devicetree ABI break for older DTS files that rely this
flag for RMII configuration. Adding this back in ensures that the older
DTBs will not break.

Fixes: db400061b5e7 ("net: cadence: macb: sama7g5_emac: Remove USARIO CLKEN flag")
Signed-off-by: Ryan Wanner <Ryan.Wanner@...rochip.com>
