Summary	0002348: Add ethernet clock source detection for fsvybrid in U-Boot
Description	The ethernet clock is still not very reliable on Vybrid. We will apply a hardware modification to provide the PHY clock via the CKO1 clock output. This should work much better. Whether this hardware modification is done and the CKO1 clock should be used instead of the internal RMII clock can be detected by a flag in the features entry of the NBoot args. This requires at least NBootVyb VN11.
