[libcamera-devel] [PATCH 09/15] ipa: ipu3: Convert to pragma once

[Kieran Bingham]

Remove the verbose #ifndef/#define/#endif pattern for maintaining
header idempotency, and replace it with a simple #pragma once.

This simplifies the headers, and prevents redundant changes when
header files get moved.
