Looks like you just enable clock output from DA850. You also need to setup PHY to accept RMII clock from MAC.
This can be done with something like this...

static int angelo_board_phy_fixup(struct phy_device *phy)
{
	phy->dev_flags |= MICREL_PHY_50MHZ_CLK;
	return 0;
}

static void __init angelo_board_init(void)
{
	phy_register_fixup_for_uid(PHY_ID_KSZ8031, MICREL_PHY_ID_MASK,
					   angelo_board_phy_fixup);

	// Old board init
}
