partial fix of changes from
"staging: drm/imx: Add support for VGA via TVE on i.MX53"
Have to call imx_drm_crtc_panel_format_pins in imx_drm_crtc_panel_format
with the correct pins instead of (0, 0) This enables configuration of
correct waveforms for vsync / hsync for parallel display, LDB (i.MX53 and
i.MX6) as well as HDMI and MIPI (i.MX6)

This adds display interface timings for the Television Encoder
connected to IPU DI1 on i.MX53 and adds some configuration
glue code to select which IPU signal generators / pins are to
be used for HSYNC/VSYNC signals.
The default configuration is pin2/pin3 for hsync/vsync. The
VGA connector on i.MX53-QSB uses pin7/pin8, and the analog
part of the DVI-I connector on MBa53 connects to pin4/pin6.

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

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)
