MLX5_GENERAL_OBJECT_TYPES types bitfield is 64-bit field.
Defining an enum for such bit fields on 32-bit platform results in below
warning.
./include/vdso/bits.h:7:26: warning: left shift count >= width of type [-Wshift-count-overflow]
^
./include/linux/mlx5/mlx5_ifc.h:10716:46: note: in expansion of macro ‘BIT’
MLX5_HCA_CAP_GENERAL_OBJECT_TYPES_SAMPLER = BIT(0x20),
^~~
Use 32-bit friendly left shift.
Fixes: 2a2970891647 ("net/mlx5: Add sample offload hardware bits and structures")
