Subject: [PATCH AUTOSEL for 4.4 132/167] ARM: imx: Add MXC_CPU_IMX6ULL and
 cpu_is_imx6ull

From: Leonard Crestez <leonard.crestez@....com>

[ Upstream commit b3ea575770c7eeb259c77b6861cd14d00eb309df ]

Support for imx6ull is already present but it's based on
of_machine_is_compatible("fsl,imx6ull") checks. Add it to the MXC_CPU_*
enumeration as well.

This also fixes /sys/devices/soc0/soc_id reading "Unknown".
