This series adds taprio offload support for ICSSG driver.

Patch [1/2] of the series moves some structures and API definition to .h
files so that these can be accessed by taprio (icssg_qos.c) file.

Patch [2/2] of the series introduces the taprio support for icssg driver.

Changes from v7 to v8:
*) Modified commit message of patch 2/2 to state both ICSSG Switch and
   dual-emac firmware supports taprio offload as pointed out by
   Andrew Lunn <andrew@lunn.ch>
*) Rebased on latest net-next/main

Changes from v6 to v7:
*) Rebased on 6.10-rc1.
*) Removed RFC tag, no functional changes.

Changes from v5 to v6:
*) Added RFC tag as net-next is closed now.
*) Created a new patch for "the struct definition move" and made this
   series instead of single patch as suggested by
   Paolo Abeni <pabeni@redhat.com>.
*) Removed est_new structure as that is no longer used.
*) Freeing qos.tas.taprio_admin using taprio_offload_free() as suggested
   by Paolo Abeni <pabeni@redhat.com>
*) Clearing taprio_admin and taprio in error case in emac_taprio_replace()
   API using goto label taprio_clear.
*) Added RB tag of Simon Horman <horms@kernel.org> 

Changes from v4 to v5:
*) Rebased on latest net-next/main [commit 5c4c0edca68a]
*) Moved icss_iep structure to icss_iep.h file so that iep wraparound time
   which is stored in iep->def_inc, can be accessed by qos file.
*) Added comment about IEP wraparound time compensation in icssg_qos.c
*) Moved icssg_qos_tas_init() to prueth_netdev_init() so that icssg_qos_tas_init()
   gets called even if interface is down.
*) Fixed print statements as suggested by Vladimir Oltean <vladimir.oltean@nxp.com>
*) Added taprio_offload_get() and taprio_offload_free() in emac_taprio_replace()
   and emac_taprio_destory() respectively.

Changes from v3 to v4:
*) Rebased on the latest next-20231005 linux-next.
*) Addressed Roger and Vinicius' comments and moved all the validations to
   emac_taprio_replace() API.
*) Modified emac_setup_taprio() API to use switch case based on taprio->cmd
   and added emac_taprio_destroy() and emac_taprio_replace() APIs.
*) Modified the documentation of structs / enums in icssg_qos.h by using
   the correct kdoc format.

Changes from v2 to v3:
*) Rebased on the latest next-20230928 linux-next.
*) Retained original authorship of the patch.
*) Addressed Roger's comments and modified emac_setup_taprio() and
   emac_set_taprio() APIs accordingly.
*) Removed netif_running() check from emac_setup_taprio().
*) Addressed Vinicius' comments and added check for MIN and MAX cycle time.
*) Added check for allocation failure of est_new in emac_setup_taprio().

Changes from v1 to v2:
*) Rebased on the latest next-20230921 linux-next.
*) Dropped the RFC tag as merge window is open now.
*) Splitted this patch from the switch mode series [v1].
*) Removed TODO comment as asked by Andrew and Roger.
*) Changed Copyright to 2023 as asked by Roger.
