The whole dispc irq handling system we currently have is only needed for
compat layer, and thus can be moved from dispc.c to the compat layer.
This is quite straigtforward, but we need to add new dispc functions to
request and free the actual hardware irq: dispc_request_irq() and
dispc_free_irq().

We have two functions to wait for a dispc interrupt:
int omap_dispc_wait_for_irq_timeout(u32 irqmask, unsigned long timeout);
int omap_dispc_wait_for_irq_interruptible_timeout(u32 irqmask,
Of these, the former is not used at all, and can be removed. The latter
is only used by the compat layer, and can be moved to the compat layer
code.

dispc_mgr_enable_sync and dispc_mgr_disable_sync are only used with the
compat mode. Non-compat will use the simpler enable and disable
functions.
This patch moves the synchronous enable/disable code to the compat
layer. A new file is created, dispc-compat.c, which contains low level
dispc compat code (versus apply.c, which contains slightly higher level
compat code).
