Subject: v3d: Drop maximum number of texture units down to 16.
X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=060575bea8e98c28938d08f953864cbd46447ed8

v3d: Drop maximum number of texture units down to 16.

This is the GLES 3.2 minmax, and also what the closed source driver does.
Avoids hitting OOMs in the CTS's
dEQP-GLES3.functional.texture.units.all_units.only_cube.1.
