r600: Fix maximum line width
There are only 13 bits available to store the line width, hence
it can't be larger than 8191
v2: Add Fixes tag
v3: - Unify value since for all r600 archs (Konstantin Kharlamov)
- Correct the value the line width value is emitted as a 12.4
fixed point value of 1/2 line width on r600-r700 and as
8 * line width on Evergreen and newer.
Fixes: 06bfb2d28f7adca7edc6be9c210a7a3583023652
r600: fork and import gallium/radeon
