[U-Boot] [PATCH] ARM: imx6q_logic: Allow optional arguments to cmd line

[Adam Ford]

This adds an extra, optional environmental variable called
'optargs' which if enabled allow additional parameters to be
passed to the kernel (ie, quiet, cma=128M, etc.)
Each script that setups the bootargs will just append this.
