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_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

Add getters for getting values in arrays: sdlb_groups and
sparx5_hsch_max_group_rate and ops out the getters, as these arrays will
differ on lan969x.

Add support for offloading ets qdisc to sparx5 switch.
The ets qdisc makes it possible to configure a mix og strict and
bandwidth-sharing bands. The ets qdisc must be attached as a root qdisc.

Add support for offloading tbf qdisc to sparx5 qdisc.
The tbf qdisc makes it possible to attach a shaper on traffic egressing
from a port or a queue. Per-port tbf qdiscs are attached as a root qdisc
directly and queue tbf qdiscs are attached to one of the classes of a
parent qdisc (such as mqprio).

Add support for offloading mqprio qdisc to sparx5 switch.
The offloaded mqprio qdisc currently does nothing by itself, but serves
as an attachment point for other qdiscs (tbf, ets etc.)
