drm/tilcdc: Enable EOF interrupts for v1 LCDC

commit 8d6c3f7 upstream. This got accidentally dropped in the fixed commit and is required for the driver to properly work on the rev1 IP, such as found on the LCDK. Fixes: 2b2080d ("drm/tilcdc: Get rid of complex ping-pong mechanism") Signed-off-by: Karl Beldan <[email protected]> Signed-off-by: Jyri Sarha <[email protected]>
