IPU's IC/IRT/VDI modules provide resizing/CSC/combination/de-interlacing
support, this patch make all these features into one processing driver.
A struct ipu_task is the interface between user and this driver, user
just need fill his task struct and queue it through ioctl, then wait
ipu hardware finish its job (now only support BLOCKING operation, not
support NO_BLOCK operation).
Pls refer to inlcude/linux/ipu.h for structure information and unit test
for usage.
This patch is for ipu driver changes.

This patch supports IPUv3 triple buffer.
Only channel 23, 27 and 28 are tested.
Test was done on MX51 BBG and MX53 SMD.
IPUv1 interface is changed accordingly
to pass building.
