when there's not.

If x86-sysfb platform-devices are removed from a system, we should
properly unload vesafb. Otherwise, we end up releasing the parent while
our vesa framebuffer is still running. This currently works just fine, but
will cause problems on handover to real hw. So add the ->remove() callback
and unregister vesafb.

This is necessary in order to make the core set file->private_data to
miscdev in use. We need that information later to dereference the
container of the device, so we can get access to our private struct from
other callbacks.

Instead of passing around struct platform_device, use struct device.
That saves one level of dereference. Also, call platform devices pdev,
and provide a shortcut for &pdev->dev.

Because uvesafb_vbe_init will fail when get zero avaiable modes,
and we have checked the return value of uvesafb_vbe_init_mode,
so it is impossible to pass NULL as mode into uvesafb_init_info.

Because uvesafb_par is allocated as part of fb_info in uvesafb_probe,
so we don't need to do NULL check for both fb_info and uvesafb_par in
uvesafb_remove.

omapdss has its own video-timings struct, but we want to move the common
videomode.
The first step is to change the omapdss's pixelclock unit from kHz to
Hz. Also, omapdss uses "pixel_clock" field name, whereas the common
videomode uses "pixelclock" field name. This patch changes the field
name also, as that makes it easy to spot any non-converted pixel_clock
uses.

The omapdss driver no longer uses get_context_loss_count call, so we can

Instead of relying on the OMAP specific
omap_pm_get_dev_context_loss_count() to detect register context loss, we
can achieve the same in a much simpler way by just observing the DISPC
registers.
We always set DISPC's load mode to LOAD_FRAME_ONLY, which is not the
reset value. Thus we can just observe the load mode to see if we have
lost register context.

Some fields in platform data structure is never used by boards.
This patch removes these fields and as a result optimizes private
driver structure a bit. Additionally patch removes backligh_power()
callback, so if it will be needed in the future, this feature should
be added as pwm{gpio,etc.}-regulator to the board code or in the DTS.
