This patch updates IPUv3 IC RGB to YUV color space conversion
matrix's parameters to align with the default VIV GPU CSC
implementation so that we may pass relevant Android CTS test
cases.

Modify mxc_vpu.c to adapt to kernel 3.10 change
- Remove all references to header files in mach folder
- Include linux/clk.h instead of mach/clock.h
- Call device_reset instead of imx_src_reset_vpu
- Dummy PU and PM api callings before they are ready
- Dummy cpu_is_mx5? api callings
- Remove VM_RESERVED flags
- Call gen_pool instead of iram_alloc
Modify mxc_vpu.h
- Change CONFIG_ARCH_MX6 to CONFIG_SOC_IMX6Q
Modify Kconfig:
- Change ARCH_MX? to SOC_IMX?, remove ARCH_MX3/ARCH_MX37
because for MX3 series only SOC_IMX31 and SOC_IMX35 are
defined in Linux 3.10, and these chips don't have VPU.
Need to add SOC_IMX37 to VPU Kconfig if MX37 could be
supported later.
Add VPU to config and build path
- mxc/Kconfig
- mxc/Makefile

add gpu freq throttle to protect SOC, when temperature
is too high, lower gpu freq to 4/64, and gpu freq will
restore when SOC cool down.

The ipu task thread checks outstanding tasks to be done on waiting
event uninterruptibly on the function find_task()'s return value.
However, sleeping on waiting event uninterruptibly contributes to
system load average value. This patch changes wait_event() to
wait_event_interruptible() to avoid the load average value inflation.

The Contiguous Memory Allocator (CMA) is mature in 3.10 kernel. Let's
change gpu driver to allocate contiguous memory from CMA pool. Doing so
will save not only the memblock reserve calls in machine code but also
the request_mem_region() and ioremap() in gpu driver. And all the
system memory will be seen by kernel no matter whether gpu driver is
running or not.
It also changes the default contiguousSize to 128 MiB for Freescale
adjustment.

This is a fast-forward porting of ipuv3 driver from 3.5.7 kernel to
kernel 3.10. The change set is kept as minimum as possible with only
making necessary code changes to adapt 3.10 kernel internal API and
framework updates. Everything else should be same as 3.5.7 one. The
change set consists of the following.
* Remove unused Kconfig options MXC_IPU_V3D, MXC_IPU_V3EX and
MXC_IPU_V3H
* Comment out busfreq calls
* Move ipu-v3.h into include/linux/, and remove all <mach/*> includes
* Drop __devinit and __devexit
* Remove assignment of pltfm_data->pg = imx6q_ipu_pg;
* Use generic device_reset() API rather than ipu_pltfm_data->init()
hook to reset IPU
* Includes <linux/sched/rt.h> ipu_device.c to fix undeclared
MAX_USER_RT_PRIO error
* Change compatible string to "fsl,imx6q-ipu" to align with community
kernel
* Define irq_sync before irq_err in DTS to align with community kernel
* Drop "ipu1_" and "ipu2_" from clock names to save the handling of the
second parameter of devm_clk_get()
* Remove the buggy csi_clk setup in ipu_clk_setup_enable() and validate
the clock before operate on it in ipu_csi_enable_mclk()
* Replace iram API (linux/iram_alloc.h) with generic memory pool API
(linux/genalloc.h) in VDOA driver
