[Mesa-dev] [PATCH v2] st/mesa: only define GLSL 1.4 for compat if driver supports it

[Christian Gmeiner]

Currently GLSL 1.4 is defined for all gallium drivers even only
GLSL 1.2 is supported as seen on etnaviv.

v1 -> v2:
 - use _min(..) as suggested by Lucas Stach and Michel Dänzer

Fixes 4560aad780b ("mesa: add GLSLVersionCompat constant")
