media: mediatek: vcodec: Drop platform_get_resource(IORESOURCE_IRQ)
Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource
from DT core") removed support for calling platform_get_resource(...,
IORESOURCE_IRQ, ...) on DT-based drivers, but the probe() function of
mtk-vcodec's encoder was still making use of it. This caused the encoder
driver to fail probe.
Since the platform_get_resource() call was only being used to check for
the presence of the interrupt (its returned resource wasn't even used)
and platform_get_irq() was already being used to get the IRQ, simply
drop the use of platform_get_resource(IORESOURCE_IRQ) and handle the
failure of platform_get_irq(), to get the driver probing again.
