[U-Boot] [PATCH v1 4/4] ARM: vf610: ddrmc: do not write CR79 by default

From: Stefan Agner <stefan.agner@toradex.com>

The current value CTLUPD_AREF(0) is the reset value of the register,
so there is no need to write a value. If needed, the register can be
written using board specific CR settings.
