It turns out that the logical CPU mapping is useful even when !CONFIG_SMP
for manipulation of devices like interrupt and power controllers when
running a UP kernel on a CPU other than 0. This can happen when kexecing
a UP image from an SMP kernel.

In the future, multi-cluster systems running AMP configurations will
require something similar for mapping cluster IDs, so it makes sense to
decouple this logic in preparation for this support.

BSYM macro is only needed for assembly files and its usage in c files is
wrong, so remove it. The linker will correctly set bit 0 for Thumb2
kernels.

The restart support was missed from the initial imx6q submission.
The mxc_restart() does not work for imx6q.  Instead, this patch adds
the restart for imx6q.

This patch uses the new cpu_logical_map() macro for converting logical
CPU numbers into physical numbers when releasing CPUs during the SMP
boot and CPU hotplug paths.

It adds a number of core drivers support for imx6q, including clock,
General Power Controller (gpc), Multi Mode DDR Controller(mmdc) and
System Reset Controller (src).
