[U-Boot] [PATCH V2 4/5] imx: mxs: reimplement get_cpu_rev

[Peng Fan]

Rewrite get_cpu_rev, from "static const char *get_cpu_rev(void)" to
"u32 get_cpu_rev(void)". To align with get_cpu_rev of other i.MXes.

Also write get_imx_type to replace get_cpu_type, since we have
macro named get_cpu_type.

[U-Boot] [PATCH V2 5/5] imx-common: consolidate macros and prototypes into sys_proto.h

[Peng Fan]

Move most macro definitions and prototypes into
"arch/arm/include/asm/imx-common/sys_proto.h" to avoid duplicated
function prototypes and marco definitions for different i.MX SoCs.

This patch do not remove the sys_proto.h for different i.MX SoCs,
because we need to modify lots of driver code and others. This patch
remove duplicated macros and prototypes and incude "sys_proto.h"
of imx-common for each sys_proto.h of different i.MX platforms.
Then later we should avoid add stuff in sys_proto.h of each platform,
and modify driver to include common sys_proto.h.
