[PATCH 03/16] media: iris: Introduce set_preset_register as a vpu_op

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

From: Dikshita Agarwal <dikshita.agarwal@oss.qualcomm.com>

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

Move set_preset_register 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.
