staging: omapdrm: Fix DMM sparse warnings 

Fix the following sparse warnings:

drivers/staging/omapdrm/omap_dmm_tiler.c:123:13:
   warning: symbol 'omap_dmm_irq_handler' was not declared.
   Should it be static?

drivers/staging/omapdrm/omap_dmm_tiler.c:370:24:
   warning: Using plain integer as NULL pointer
