ARM: imx6: build pm-imx6q.c independently of CONFIG_PM

When building a kernel image with only CONFIG_CPU_IDLE but no CONFIG_PM,
we will get the following link error.

Since pm-imx6q.c has been a collection of library functions that access
CCM low-power registers used by not only suspend but also cpuidle and
other drivers, let's build pm-imx6q.c independently of CONFIG_PM to fix
above error.

ARM: imx: add support code for IMX50 based machines

Add machine support code for the Freescale IMX50 SoC.

The IMX50 is quite similar to the Freescale IMX53, and contains many of the
same periperhal hardware modules, at the same address offsets as the IMX53.
(Notable exceptions are that the IMX50 contains no CAN bus hardware, less
GPIO, no VPU, it does contain an Electrophoretic display controller though).

This support code uses some of the IMX53 setup code to reduce duplication
of what would be identical init IO setup.

One register may have several fields to control some clocks. It
is possible that the read/write values of some fields may map to
different real functional values, so writing to the other fields
in the same register may break a working clock tree. A real case
is the aclk_podf field in the register 'CCM Serial Clock Multiplexer
Register 1' of i.MX6Q/SDL SoC. This patch introduces a fixup hook
for multiplexer clock which is called before writing a value to
clock registers to support this kind of multiplexer clocks.

Pull ARM SoC platform updates (part 3) from Arnd Bergmann:
"This is the third and smallest of the SoC specific updates. Changes
include:

- SMP support for the Xilinx zynq platform
- Smaller imx changes
- LPAE support for mvebu
- Moving the orion5x, kirkwood, dove and mvebu platforms to a common
"mbus" driver for their internal devices.

It would be good to get feedback on the location of the "mbus" driver.
Since this is used on multiple platforms may potentially get shared
with other architectures (powerpc and arm64), it was moved to
drivers/bus/. We expect other similar drivers to get moved to the
same place in order to avoid creating more top-level directories under
drivers/ or cluttering up the messy drivers/misc/ even more."
