[U-Boot] [PATCH] powerpc/fman/memac: use default MDIO_HOLD value

From: Shaohui Xie Shaohui.Xie@freescale.com
Current driver uses a Maximum value for MDIO_HOLD when doing 10G MDIO access, this is due to an errata A-006260 on T4 rev1.0 which is fixed on rev2.0, so remove the maximum value to use the default value for rev2.0.
