This patch set adds the support of Hisilicon BMC Gigabit Ethernet Driver.

This patch set includes basic Rx/Tx functionality. It also includes
the registration and interrupt codes.

This work provides the initial support to the HIBMCGE and
would incrementally add features or enhancements.

Closes: https://lore.kernel.org/oe-kbuild-all/202408200026.q20EuSHC-lkp@intel.com/
v1: https://lore.kernel.org/all/20240819071229.2489506-1-shaojijie@huawei.com/
RFC v2 -> v1:
- Use FIELD_PREP/FIELD_GET instead of union, suggested by Andrew.
- Delete unnecessary defensive code, suggested by Andrew.
- A few other minor changes.
RFC v2: https://lore.kernel.org/all/20240813135640.1694993-1-shaojijie@huawei.com/
RFC v1 -> RFC v2:
- Replace linkmode_copy() with phy_remove_link_mode() to
simplify the PHY configuration process, suggested by Andrew.
- Delete hbg_get_link_status() from the scheduled task, suggested by Andrew.
- Delete validation for mtu in hbg_net_change_mtu(), suggested by Andrew.
- Delete validation for mac address in hbg_net_set_mac_address(),
suggested by Andrew.
- Use napi_complete_done() to simplify the process, suggested by Joe Damato.
- Use ethtool_op_get_link(), phy_ethtool_get_link_ksettings(),
and phy_ethtool_set_link_ksettings() to simplify the code, suggested by Andrew.
- Add the null pointer check on the return value of pcim_iomap_table(),
suggested by Jonathan.
- Add the check on the return value of phy_connect_direct(),
suggested by Jonathan.
- Adjusted the layout to place the fields and register definitions
in one place, suggested by Jonathan.
- Replace request_irq with devm_request_irq, suggested by Jonathan.
- Replace BIT_MASK() with BIT(), suggested by Jonathan.
- Introduce irq_handle in struct hbg_irq_info in advance to reduce code changes,
suggested by Jonathan.
- Delete workqueue for this patch set, suggested by Jonathan.
- Support to compile this driver on all arch in Kconfig,
suggested by Andrew and Jonathan.
- Add a patch to add is_valid_ether_addr check in dev_set_mac_address,
suggested by Andrew.
- Use macro instead of inline to fix the warning about compile-time constant
in FIELD_PREP(), reported by Simon Horman.
- A few other minor changes.
