This patch replaces the code for getting an unsigned long from a
userspace buffer by a simple call to kstroul_from_user.
This makes it easier to read and less error prone.

Clean up the GTT code a bit, make the pages uncached and go via the proper
interfaces. This avoids any aliasing problems.

On the CPU side we need to access the pages via their true addresses not via
the GTT. This is fine for GEM created fb objects for X. For the kernel fb
when not in stolen RAM we are going to need to use vm_map_ram() and hope we
have enough virtual address space to steal.

In case kzalloc() fails the second or third time
we should free the previous allocated resources.
In order to keep one return point and to keep the cleanup code to one
place, some reordering was necessary.

Also while at it, removed the *sizeof(char) - to quote Linus:
"" Also removed the silly "* sizeof(u8)".  If that isn't 1, we have way
   deeper problems than a simple multiplication can fix. """

This patch transforms drivers/staging/dt3155v4l driver to use videobuf2 framework.
Tested and works with "xawtv -f".

Either streaming API or read method should be selected during kernel configuration.

If both are selected into the driver (not possible without another patching),
either due to my misunderstanding or problems in xawtv (or both), I get kernel panic
after some start/stop of xawtv (not strictly reproducible).
