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.

ChangeLog:
v10 -> v11:
- Delete devm_netdev_alloc_pcpu_stats to prevent memory leak,
suggested by Jakub.
- Use the same pattern for 'control' and 'ctrl', suggested by Christophe JAILLET.
- hbg_mdio_init_hw() return void because no error patch,
suggested by Christophe JAILLET.
