ipu_reset() can fail with a timeout. Check the return value and act
appropriately.

CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.

This has been added once, but does not seem to be necessary. Tested
on i.MX51 and i.MX6.

YVYU is not supported by the IPU, so remove partial handling
of this format and replace it with YUYV which is supported.

Indication of succesful probe is more useful than stating that the

IPU Interrupt numbers and the various IPU submodules base addresses are
more interesting for debugging purposes rather than normal use, so use
dev_dbg instead.

The IPU is the Image Processing Unit found on i.MX51/53/6 SoCs. It
features several units for image processing, this patch adds support
for the units needed for Framebuffer support, namely:
- Display Controller (dc)
- Display Interface (di)
- Display Multi Fifo Controller (dmfc)
- Display Processor (dp)
- Image DMA Controller (idmac)
This patch is based on the Freescale driver, but follows a different
approach. The Freescale code implements logical idmac channels and
the handling of the subunits is hidden in common idmac code pathes
in big switch/case statements. This patch instead just provides code
and resource management for the different subunits. The user, in this
case the framebuffer driver, decides how the different units play
together.
The IPU has other units missing in this patch:
- CMOS Sensor Interface (csi)
- Video Deinterlacer (vdi)
- Sensor Multi FIFO Controler (smfc)
- Image Converter (ic)
- Image Rotator (irt)
