[PATCH 6.8 511/715] drm/xe: Replace 'grouped target' in Makefile with pattern rule

[Sasha Levin]

From: Dafna Hirschfeld <dhirschfeld@xxxxxxxxx>

[ Upstream commit e62d2e00780b4a465c77d2229837495fcbc480d3 ]

Since 'grouped target' is used only in 'make' 4.3, it should
be avoided. Replace it with 'multi-target pattern rule' which
has the same behavior.

Fixes: 9616e74b796c ("drm/xe: Add support for OOB workarounds")
