Add dummy cpu type MXC_CPU_MX6QP/DP. Since i.MX6QP use a revision 2, but with cpu type i.MX6Q, we need the MXC_CPU_MX6QP and to decrease major with 1 to let print_cpuinfo print the correct info.
This patch also fix is_mx6dqp(), since get_cpu_rev can return MXC_CPU_MX6QP and MXC_CPU_MX6DP, we should use: (is_cpu_type(MXC_CPU_MX6QP) || is_cpu_type(MXC_CPU_MX6DP)).
