1b409828b1 imx: mx7ulp: Add soc level initialization codes and functions
Implement soc level functions to get cpu rev, reset cause, enable cache,
etc. We will disable the wdog and init clocks in s_init at very early u-boot
phase.

Since the we are seeking the way to get chip id for mx7ulp, the get_cpu_rev
is hard coded to a fixed value. This may change in future.

Reuse some code in imx-common.

Add i.MX6SLL cpu type.
MXC_CPU_MX6D is not a real value in chip, so change it to 0x6A.

37cf215253 imx: vf610 add get_cpu_rev
Since we need to support runtime check for different drivers, we need
to add get_cpu_rev for vf610, otherwise there will be build errors.

This patch introduces a dummy CPU id which is not read from chip
silicon. Later when we can get the real id from chip, can fix the
value of MXC_CPU_VF610 then.

Add MXC_CPU_MX6UL for i.MX6UL CPU type which is got at runtime from
DIGPROG register. But the value has been occupied by MXC_CPU_MX6D which
is not real id from DIGPROG register, so change i.MX6D to value 0x67 which
was not occupied.

d0acd99334 imx: add cpu type for i.MX6QP/DP
Add cpu type for i.MX6QP/DP.

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)).
