[PATCH net-next 12/15] net: sparx5: use is_sparx5() macro throughout

[Daniel Machon <daniel.machon@microchip.com>]

Use the is_sparx5() macro (introduced in earlier series [1]), in places
where we need to handle things a bit differently on lan969x.

These places are:

    - in sparx5_dsm_calendar_update() we need to switch the calendar
      from a to b on lan969x.

    - in sparx5_init_coreclock() we need to set the policer update
      internal (pol_upd_int) to 820 for the new core clock frequency on
      lan969x.

    - in sparx5_start() we need to make sure the HSCH_SYS_CLK_PER
      register is only touched on Sparx5.

    - in sparx5_start() we need to disable VCAP and FDMA for lan969x
      (will come in later series).

    - in sparx5_mirror_port_get() we must make sure the
      ANA_AC_PROBE_PORT_CFG1 register is only read on Sparx5.

    - sparx5_netdev.c and sparx5_packet.c we need to use different IFH
      (Internal Frame Header) offsets for lan969x.

    - in sparx5_port_fifo_sz() we must bail out on lan969x.

    - in sparx5_port_config_low_set() we must configure the phase
      detection registers.

    - in sparx5_port_config() and sparx5_port_init() we must do some
      additional configuration of the port devices.

    - in sparx5_dwrr_conf_set() we must derive the scheduling layer
