Subject: [PATCH net-next v3 00/13] net: airoha: Add AN7583 ethernet
 controller support

Introduce support for AN7583 ethernet controller to airoha-eth dirver.
The main differences between EN7581 and AN7583 is the latter runs a
single PPE module while EN7581 runs two of them. Moreover PPE SRAM in
AN7583 SoC is reduced to 8K (while SRAM is 16K on EN7581).

---
Changes in v3:
- improve device-tree binding
- rebase on top of net-next main branch
- Link to v2: https://lore.kernel.org/r/20251016-an7583-eth-support-v2-0-ea6e7e9acbdb@kernel.org

Changes in v2:
- rely on IS_ENABLED(CONFIG_NET_AIROHA_FLOW_STATS) instead of ifedef
  CONFIG_NET_AIROHA_FLOW_STATS in airoha_ppe_get_num_stats_entries
  routine
- return number of stats_entries from airoha_ppe_get_num_stats_entries()
  and airoha_ppe_get_total_num_stats_entries()
- remove magic number in airoha_ppe_foe_commit_sram_entry routine
- improve code readability in airhoha_set_gdm2_loopback routine adding
  some macros
- improve commit logs
- remove magic numbers in airoha_ppe_foe_get_entry_locked()
- Link to v1: https://lore.kernel.org/r/20251015-an7583-eth-support-v1-0-064855f05923@kernel.org
