Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.

Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content.  (both just wrap <asm-generic/errno.h>)

Replace all include directives for <asm/errno.h> with <linux/errno.h>.

This patch moves the following functions into the imx-common
directory:

- mxs_wait_mask_set()
- mxs_wait_mask_clr()
- mxs_reset_block()

These are currently used by i.MX28. But the upcoming GPMI NAND port
for i.MX6 will also use these functions. So lets move them to a
common location to re-use them.
