[dpdk-dev] [PATCH v4 02/14] common/mlx5: add color register idle bits definition

[Li Zhang <lizh@nvidia.com>]

From: Shun Hao <shunh@nvidia.com>

8 bits are used for meter color in meter register. When the meter
register can be shared, the rest 24 bits can be used by others.
This adds the definination for the 24 bits that can be shared.
