CONFIG_FB_DEFERRED_IO is defined as bool while CONFIG_FB is defined as
tristate. Currently fb_defio.o is linked into the kernel image even if
CONFIG_FB=m.

I fix this by updating the Makefile to link fb_defio.o into fb.o and thus
go into one place with the other core framebuffer code.

fb_deferred_io_fsync() returns the value of schedule_delayed_work() as
an error code, but schedule_delayed_work() does not return an error. It
returns true/false depending on whether the work was already queued.

Fix this by ignoring the return value of schedule_delayed_work().

Instead of having fbdev framework core files at the root fbdev
directory, mixed with random fbdev device drivers, move the fbdev core
files to a separate core directory. This makes it much clearer which of
the files are actually part of the fbdev framework, and which are part
of device drivers.
