i965/surface_formats: add support for 2D ASTC surface formats
Define two-thirds of the 2D Intel ASTC surface formats (LDR-only). This allows a 1-to-1 mapping from the mesa format to the Intel format. ASTC textures will default to being processed in LDR mode. If there is hardware support for HDR/Full mode and the texture is not sRGB, add the format bit necessary to process it in HDR/Full mode. v2: remove extra newlines. v3: follow existing coding style in translate_tex_format(). v4: expound on the GEN9_SURFACE_ASTC_HDR_FORMAT_BIT comment. update SF table - ASTC is actually supported in Gen8. v5: conform the ASTC MESA_FORMAT enums to the existing naming convention.
