[PATCH] ARM: i.MX7/8M: Fix boot source detection on i.MX8MP

[PATCH] ARM: i.MX7/8M: Fix boot source detection on i.MX8MP

[Uwe Kleine-König]

On i.MX8MP the indicator for serial boot is 14, which is different from
the value found for i.MX8MM. So consider 14 as serial boot, too and
document the machines where the respective values are found.
