[U-Boot] [PATCH] imx: don't clobber reset cause

The cause of a reset is generally useful, and shouldn't be
blindly cleared in the process of displaying it as a part
of the boot announcement.

If a particular system wants to clear it out, this should
be done later after there's an opportunity for code or
boot commands to read the value.
