Subject: [PATCH v2 3/5] media: chips-media: wave5: separate irq setup routine

Separate interrupts setup routine to reduce code duplication. Also
enable interrupts based on vpu_attr->support_encoders and
vpu_attr->support_decoders fields to facilitate other Wave5xx IPs
support, because not all of them are both encoders and decoders.
