[Mesa-dev] [PATCH 3/3] i965/tex_image: Avoid the ASTC LDR workaround on gen9lp

[Nanley Chery]

Both the internal documentation and the results of testing this in the
CI suggest that this is unnecessary. Add the fixes tag because this
reduces an internal benchmark's startup time significantly. Eero
reported that a less optimal version of this patch reduced the startup
time of the benchmark by about 14 seconds.
