video: da8xx-fb: enable sync lost intr for v2 ip

From: Afzal Mohammed <[email protected]>

The interrupt handler explicitly has code that handles the sync lost interrupt. However the sync lost interrupt is never actually being enabled in the LCD controller, therefore this interrupt code path is not being exercised. This fix simply enables the generation of the sync lost interrupt by the LCD controller so it can be dealt with appropriately by the interrupt handler.
