IPU_CONF_..._EN bits are implementation details, not to be made public.
Add wrappers around ipu_module_enable/disable, so the CSI V4L2 driver
can enable/disable the CSI and SMFC modules.

This function returns the currently active buffer (0 or 1)
of a double buffered IDMAC channel. It is to be used by the
CSI driver.

The Sensor Multi Fifo Controller (SMFC) is used as a buffer between
the two CSIs (writing simultaneously) and up to four IDMAC channels.

The i.MX Image Processing Unit (IPU) contains a number of image processing
blocks that sit right in the middle between DRM and V4L2. Some of the modules,
such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS
Sensor Interface (CSI) and their FIFOs could be assigned to either framework,
but others, such as the dma controller (IDMAC) and image converter (IC) can
be used by both.
The IPUv3 core driver provides an internal API to access the modules, to be
used by both DRM and V4L2 IPUv3 drivers.
