The function stmp_reset_block() provides the exactly same functionality
as mxs_reset_block(). So use stmp_reset_block() instead, so that
<mach/common.h> inclusion can be removed.

The header <mach/hardware.h> is not needed at all, and <mach/mxs.h> is
needed only for macros MXS_SET_ADDR and MXS_CLR_ADDR. Define the macros
and remove the mach header inclusions.

Instead of using static address definition, get reset address from
device tree with mapping, so that core_initcall mxs_arch_reset_init()
can be killed.
The "rtc" clock code in mxs_arch_reset_init() seems to be zombie, since
there is no clk lookup defined in clock driver at all. Remove it
together.

There is no user of function mxs_reset_block() now. Let's move
mxs_restart() into mach-mxs.c as a static function and remove system.c
completely.

Instead of using the static definitions, get ocotp base address from
device tree with mapping.

The only user of the static mapping done in mx23_map_io and mx28_map_io
is low-level debug now. Use debug_ll_io_init() instead, so that the
static mapping is used nowhere and can be removed completely later.

Most of the function hooks are same between imx23 and imx28
machine_desc, so merge them into one.

Most of the stuff in the headers are used nowhere now. Move a few
things that are useful for mach-mxs.c into there and remove the headers.
