We have dev_add_param_enum() now, so use it for the mode_name
setting. Also drop the special case for single mode framebuffers,
just add the mode_name parameter for this case aswell.

And use it inside struct fb_info. This struct has the advantage
that the supported modes can be passed around in a single pointer.

barebox does not need the screen size directly, but we pass the
framebuffer to Linux via simnplefb it is desirable to pass the
full size of the framebuffer. Default to calculated values from
the screen resolution.

The IPU has a fractional pixelclock divider. When used, this produces
clock jitter which especially LVDS transceivers can't handle. Allow
to disable it via platform_data.

When requested 32bit formats the IPU generated a 24bit format instead.
Implement real 32bit format (xxrrggbb) and let the IPU generate a 24bit format
when requested.

No need to hardcode the channel parameters for the rgb offsets,
we can calculate them from the fb_bitfields. ipu_ch_param_write_field()
is the same as is the mainline IPUv3 driver.

bitfields are not portable and one should make assumptions of the
layout of bitfields. Replace them with the ipu_ch_param_write_field()
which is already used in the mainline IPUv3 driver.

With the IPU the way the display is connected is completely independent
of the framebuffer pixel format. So instead of specifying a pixel width
in platform_data we have to specify how the display is connected.

Add support for framebuffers with noncontiguous horizontal lines.
Video drivers can set this value if the hardware requires it.
In case a driver does not set it, the current value of
xres * (bpp / 8) is used instead.

MXS specific devices have some common infrastructure in the kernel
known as STMP devices. We have the same in barebox, but with a
mxs_ prefix instead of a stmp_ prefix. As some STMP devices are
also found on i.MX6 move the common infrastructure out of MXS
specific files and use the stmp_ prefix.
This is done in preparation for i.MX6 NAND support.

On the MX27 based board phycard-i.MX27 the display won't properly
come up.
Before removing imx-regs.h and the code that sets the register
in the i.MX video driver, the PCCR registers were set _after_
the screen start (LSSAR) was set.
This restores that old behaviour and makes the display come up
properly again.
I did not have a chance to test this on any other i.MX27 or i.MX21
hardware though I assume that the "old" order is required there
too.
