We should propagate the error code returned by 'fb_alloc_cmap()' instead
of returning -EFAULT.

There is no need to shut gcc up. It should not complain.
Axe 'fbdev', it is never used in this function.

Rewrite the exit path based on 'au1200fb_drv_remove()'.
We can safely iterate for all already handled planes. Even if not
completely initialized, the functions that are called will silently accept
the 'fb_info' structure that is passed.
As soon as we find a NULL in the '_au1200fb_infos' array, we know that we
have released all what we needed to release. So we can 'break'.

'au1200fb_drv_probe()' can not fail after a successful call to
'request_irq()'. So there is no point to call 'free_irq()' in the error
handling path.
Moreover, the hard coded AU1200_LCD_INT looks boggus since
commit 1630d85a8312 ("au1200fb: fix hardcoded IRQ").
So, remove it.

We should go through the error handling code instead of returning -ENOMEM
directly.

'ret' is known to be 0 at this point.
In case of memory allocation error in 'framebuffer_alloc()', return
-ENOMEM instead.

If 'fb_alloc_cmap()' fails, 'fbi->pseudo_palette' is freed and an error
code is returned by 'au1200fb_init_fbinfo()'.
The only caller, 'au1200fb_drv_probe()' goes to an error handling path
where resources allocated in 'fb_alloc_cmap()' are freed.
This leads to a double free of 'fbi->pseudo_palette'.
Fix it by letting the caller free all resources in case of failure in
'au1200fb_init_fbinfo()'.

dmam_alloc_noncoherent is a trivial wrapper around dmam_alloc_attrs,
that hardcodes one particular flag. Make the devres code more
flexible by allowing the callers to pass arbitrary flags.

This patch changes all absolute SYS_XY registers to offsets from the
SYS block base, prefixes them with AU1000 to avoid silent failures due
to changed addresses, and introduces helper functions to read/write
them.
No functional changes, comparing assembly of a few select functions shows
no differences.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.
