mlxsw: spectrum_buffers: Convert mlxsw_sp_port_headroom_init()
Currently mlxsw_sp_port_headroom_init() configures both priomap and buffers by hand. Additionally, for port buffers, it configures buffer 0 with a size that it will never again have if PFC configuration is touched. Rewrite the init code to become a client of the new hdroom code. The only difference in invocation is that the configuration is forced, so that it is issued even if the desired configuration happens to match what is contained in (hitherto not initialized with meaningful values) mlxsw_sp_port->hdroom. Since now mlxsw_sp_port_headroom_init() initializes all the PG buffers to meaningful values, mlxsw_sp_hdroom_configure_buffers() can avoid querying the current configuration, and can fill the whole PBMC itself.
