radv: round up max_lds_per_simd / lds_per_wave

Browse source 
If each SIMD has to get an different number of waves, report the maximum.

One example of a situation is when a single-wave workgroup uses more than
max_lds_per_simd. This change causes radv_get_max_waves() to report a
single wave per SIMD instead of none.
