mx35 iomux: correct offsets of IOMUX registers

This makes mxc_iomux_set_input() work correctly.  Previously, the
incorrect offset of IOMUXSW_INPUT_CTL caused mxc_iomux_set_input()
to write to the wrong register, possibly resulting in unexpected
behaviour.

ARM: mx6: define CONFIG_ARM_ERRATA_742230

The ARM errata 742230 - "ARM errata: DMB operation may be faulty" is
claimed for Cortex-A9 (r1p0..r2p2).  Though i.MX6 uses a newer revision
than r2p2, we are seeing a reboot failure on i.MX6 SMP build that can be
fixed by applying the workaround for this errata.  So for safety, let's
define CONFIG_ARM_ERRATA_742230 to enable the workaround on i.MX6.

imx: Move some header files from arch-mxs to imx-common

The following headers are moved to a i.MX common location:

- regs-common.h
- regs-apbh.h
- regs-bch.h
- regs-gpmi.h
- dma.h

This way this header can be re-used also by other i.MX platforms.
For example the i.MX6 which will need it for the upcoming NAND
support.

imx: Move some i.MX common functions into the imx-common directory

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.

imx: mx6q_4x_mt41j128.cfg: Setup CCM_CCOSR register

Setup CCM_CCOSR register to provide a CKO1 clock frequency of 16.5 MHz.

CKO1 drives sgtl5000 codec clock on mx6qsabrelite and doing this setup in the
bootloader will allow us to remove a lot of code in arch/arm/mach-imx/mach-imx6q.c
from the mainline kernel.

mx6q_4x_mt41j128.cfg is also used by mx6qsabresd, and it is safe to use it for
this board as well.

nitrogen6x: Setup CCM_CCOSR register

Doing this setup in the bootloader will allow us to remove a lot of code in
arch/arm/mach-imx/mach-imx6q.c from the mainline kernel.

Also, according to Eric Nelson: "enabling the clock <in the bootloader> will
remove squeal after an ungraceful reboot (watchdog) if hooked up to speakers."
