Several DIU registers were being initialized either unnecessarily or to
wrong values.
1) All interrupts were enabled even though there's no interrupt handler.
Interrupts were left enabled when booting Linux.
2) Don't configure a dummy area descriptor, since we don't support ADs
in U-Boot.
3) Don't configure any write-back buffer registers, since we don't use
that mode.
4) The default values for the THRESHOLDS, SYN_POL, and PLUT registers
should be used, so don't touch those registers either.

When the resolution is set to 800x600 and 1024x768,
but, the driver will use 1280x1024 resolution to set the DIU register

Update the Freescale DIU video driver (fsl_diu_fb.c) to use linux/fb.h.
Some data structures from this header file were just copied into
fsl_diu_fb.c.

The SHARP LQ084S3LG01 is a TFT LCD used on the P1022DS (revision "C") board.
This device only supports 800x600 resolution, so if that resolution is selected,
assume that this is the device. The device is attached to the LVDS port
on the P1022DS board.
The existing 800x600 entry (for the PDM360NG board) is actually 800x480,
so we fix that. To support two different 800x resolutions, the Y-resolution
is now passed to fsl_diu_init() and both values are used to pick the proper
fb_videomode structure.
The data for the 800x600 video mode is originally from Jiang Yutang.

Use the 'video-mode' environment variable (for Freescale chips that have a
DIU display controller) to designate the full video configuration. Previously,
the DIU driver used the 'monitor' variable, and it was used only to determine
the output video port.
The old definition of the "monitor" environment variable only determines
which video port to use for output. This variable was set to a number (0,
1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The
resolution was hard-coded into board-specific code. The Linux command-line
arguments needed to be hard-coded to the proper video definition string.

Since the driver is used not only on Freescale boards,
we move it to a common place for video drivers as
suggested by Wolfgang. The patch also cleans up the
top level Makefile.
