[PATCH v3 04/16] media: iris: Introduce interrupt_init as a vpu_op

[Dmitry Baryshkov]

From: Dikshita Agarwal <dikshita.agarwal@xxxxxxxxxxxxxxxx>

The interrupt_init sequence is currently shared across all supported
devices. Starting with Qualcomm QCM2290 (AR50LT), the register
programming would differ.

Move interrupt_init into a vpu_op to allow per-device customization.

This change prepares the driver for upcoming hardware variants.
No functional change so far for existing devices.
