drm/mediatek: Fix platform_get_irq() error checking

Browse source

The platform_get_irq() function returns negative error codes on failure
and positive non-zero IRQ numbers on success.  It never returns NULL. Fix
the error checking to look for negatives, and change "hdmi->irq" from
unsigned int to just int.
