Add 'optargs' variable to be set to additional kernel arguments, similar
to omap3*/am3* usage.

The common form is you set this in uEnv.txt to whatever you happen to
need (say force the display to be some resolution) and not have to
re-write the whole of mmcargs.  Or other times you want to pass in
additional args, without modifying the rest of the boot logic.
