2016 u-boot added dummy CPU types for the i.MX6QP and i.MX6DP. When doing runtime cpu type checking, we can't use CPU type of i.MX6Q and i.MX6D for them more, which is ok in 2015 u-boot. This patch adds the MXC_CPU_MX6QP and MXC_CPU_MX6DP at some places missed to do the checking. Signed-off-by: Ye Li <ye.li@nxp.com>
