ARM: do not ignore data aborts initially ...

arm_ignore_data_abort can be set to nonzero to ignore data aborts. The
default should be not to ignore data aborts. Fix this.

fb: fbconsole: Add missing blits ...

When using offscreen rendering we need some more points where we
blit the offscreen buffer to the screen. Add them.

So far we only supported blitting the whole screen from the shadow
fb to the framebuffer. Add a function to blit areas.

gui: Use fb provided shadowfb for offscreen rendering ...

The fb core now has builtin support for offscreen rendering, use
this and drop offscreen handling in the gui code.

fb: Add shadowfb support ...

For speeding up rendering we need shadow framebuffers. This is currently
implemented in the gui functions. This does not work properly when two
users (splash and fbconsole) use the same framebuffer since in this case
two different shadow framebuffers will be used. This patch implements
shadowfb handling in the fb core directly. With this the fb device gets
a parameter 'shadowfb'. When this is true the fb core will allocate a
shadow fb and provide it to the users.

splash command: depend on CONFIG_VIDEO ...

The splash command only makes sense with framebuffer support enabled, so
add the corresponding dependency to Kconfig.

video: backlight: add fallbacks for client functions ...

Add empty static inline function fallbacks if backlight support
is not enabled, so that drivers using the backlight don't fail to
build.

video: simple-panel: mode support depends on I2C and EDID ...

Reading modes from EDID EEPROMs requires both I2C and EDID support to
be available. As the simple panel driver is also useful without mode
reading support, only built it in if the requirements are met.

Fixes:
In function `simple_panel_get_modes':
simple-panel.c:88: undefined reference to `of_find_i2c_adapter_by_node'

video: imx-hdmi: sync with kernel ...

This syncs the imx-hdmi driver with Linux 4.2-rc1 where it makes sense. This
makes it easier to compare the driver with the kernel. This also adds
hdmi_av_composer which is mandatory. Somehow the driver worked without it in
lower resolutions, but now it also works for higher resolutions.
