net/mlx5: Create a new profile for SFs
Create a new profile for SFs in order to disable the command cache.
Each function command cache consumes ~500KB of memory, when using a
large number of SFs this savings is notable on memory constarined
systems.
Use a new profile to provide for future differences between SFs and PFs.
The mr_cache not used for non-PF functions, so it is excluded from the
new profile.
