Substitute home-brewed memory management for framebuffer memory with what
core mm provide us: vmalloc_32_user() and remap_vmalloc_range()
The former is designed to allocate virtually contiguous area which is
32bit addressable and zeroed so it can be mapped to userspace without
leaking data. The latter does the similar job to remap_pfn_range() but
additionally validate vmalloc'ed area and it's size.

Make vfb a bit more flexible in sense what it can represent and allow
the end user to specify video mode parameters via newly introduced module
option "mode". Since it is test module it is still up to the end user
to make sure there is enough memory to satisfy video mode settings.

Add description to "videomemorysize" and "vfb_enable" module parameters to
make them a bit friendly to the end user.

In vfb_probe memory is allocated using rvmalloc which automatically
sets the allocated memory to zero. This patch removes the second
unnecessary memset in vfb_probe.

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.
