net/mlx5: Add pages debugfs
Add pages debugfs to expose the following counters for debuggability:
fw_pages_total - How many pages were given to FW and not returned yet.
vfs_pages - For SRIOV, how many pages were given to FW for virtual
functions usage.
host_pf_pages - For ECPF, how many pages were given to FW for external
hosts physical functions usage.
