Subject: [PATCH AUTOSEL 6.8 18/43] accel/ivpu: Improve clarity of MMU error messages

From: "Wachowski, Karol" <karol.wachowski@...el.com>

[ Upstream commit 3556f922612caf4c9b97cf7337626f8342b3dea3 ]

This patch improves readability and clarity of MMU error messages.
Previously, the error strings were somewhat confusing and could lead to
ambiguous interpretations, making it difficult to diagnose issues.
