Boards can skip display interface init using board_video_skip().
If display interface was not initialized (e.g. no ipuv3 framebuffer
registered or IPU clock disabled), booting Linux stops due to the
crash in IPU shutdown function, when accessing IPU registers.
Check IPU clock and skip shutdown if clock is not enabled.

This reverts commit 1d20170467, reversing
changes made to 6aee2ab68c.
The mxc_ipuv3_fb.c changes introduce build failures on some targets.

Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content. (both just wrap <asm-generic/errno.h>)
Replace all include directives for <asm/errno.h> with <linux/errno.h>.

Discard the empty video_set_lut function from platform video
drivers.
This commit "69d275458893eaec35229b589092c2a6bde5440f" introduces
a weak function video_set_lut, so we do not need an strong function
in platform drivers, which does nothing.

This patch updates the i.MX video driver to store the
frame-buffer address in the fb_base field of the global
data structure *gd.
By doing this, you can find the frame buffer address
using the 'bdinfo' command:
U-Boot > bdinfo
arch_number = 0x00000EB9
...
FB base = 0x4F35F1C0
This is very useful when debugging display connections.

The ipuv3 driver is currently only used on mx51, but it can be extended to work
on mx53 and mx6 as well.
Rename mx51_fb_init(), so that it can be used by other SoCs.

The framebuffer driver for MX5 is based on CONFIG_LCD.
In the current implementation, there is a serious bug
because the required memory is allocated before
relocation, but the driver knows only later which is
the resolution of the display. The patch switches the driver
to CONFIG_VIDEO and the memory is allocated by the driver itself.
We also need to switch the vision2 board code and config file
in the same commit so that this commit will be bisectable.

Add framebuffer driver for the MX51 processor
working on the IPUv3 internal graphic processor.
The port is based on the driver found in the kernel
delivered by Freescale as part of i.MX BSP:
