net: hisilicon: Fix hns_mdio module autoload for OF registration 

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/net/ethernet/hisilicon//hns_mdio.ko | grep alias
alias:          platform:Hi-HNS_MDIO
alias:          acpi*:HISI0141:*

After this patch:

$ modinfo drivers/net/ethernet/hisilicon//hns_mdio.ko | grep alias
alias:          platform:Hi-HNS_MDIO
alias:          of:N*T*Chisilicon,hns-mdioC*
alias:          of:N*T*Chisilicon,hns-mdio
alias:          of:N*T*Chisilicon,mdioC*
alias:          of:N*T*Chisilicon,mdio
alias:          acpi*:HISI0141:*
