rbd: kill off the snapshot list

We no longer use the snapshot list for anything.  When we need to
look up a snapshot name, id, size, or feature mask, we just do it
directly rather than relying on this list being updated with every
refresh.  The main reason it existed was for the benefit of the
device/sysfs entries that previously were associated with snapshots.

So get rid of the snapshot list, and struct rbd_snap, and the
hundreds of lines of code that supported them.

This resolves:

OMAPDSS: DPI: fix compilation if DSI not compiled in

Commit 100c826235793345efe06b3558cc9d36166b1e26 (OMAPDSS: DPI: use new
clock calculation code) breaks dpi.c compilation if DSI is not enabled
in the kernel configuration.

Fix compilation by adding dummy inline functions for the ones that dpi.c
references. The functions will never be called, as dpi.c knows that
there is no DSI device available.

OMAPDSS: Makefile: move omapfb after panels

omapfb requires the panels to have been probed before omapfb's probe. We
currently manage that by having omapfb in late initcall level. However,
a much simpler way is to just change the makefile so that omapfb is
after the panel drivers.

OMAPFB: use module_platform_driver()

Instead of using platform_driver_probe(), use module_platform_driver()
so that we can support deferred probing.

OMAPFB: defer probe if no displays

omapfb requires the panel drivers to have been probed when omapfb is
initialized. omapfb does not support insertion of new panels after its
probe. This causes a problem in case omapdss or the panel probes have
been deferred due to EPROBE_DEFER error, as omapfb won't find any
displays.

As a quick fix, this patch changes the omapfb probe so that if omapfb
does not find any displays, it'll return EPROBE_DEFER. This is not
perfect, as with a board with no displays, omapfb will get deferred
forever. Also, if the board has multiple displays, but only some of them
have been probed, omapfb will start and leave the unprobed displays out.
