net/mlx5e: Extend TC max ratelimit using max_bw_value_msb
The per-TC rate limit was restricted to 255 Gbps due to the 8-bit
max_bw_value field in the QETC register.
This limit is insufficient for newer, higher-bandwidth NICs.
Extend the rate limit by using the full 16-bit max_bw_value field.
This allows the finer 100Mbps granularity to be used for rates up to
~6.5 Tbps, instead of switching to 1Gbps granularity at higher rates.
The extended range is only used when the device advertises support
via the qetcr_qshr_max_bw_val_msb capability bit in the QCAM register.
