[PATCH 3/7] net: hns: Fix hns_dsaf module autoload for OF registration

[Javier Martinez Canillas]

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/hns_dsaf.ko | grep alias
alias:          acpi*:HISI00B2:*
alias:          acpi*:HISI00B1:*

After this patch:

$ modinfo drivers/net/ethernet/hisilicon/hns/hns_dsaf.ko | grep alias
alias:          acpi*:HISI00B2:*
alias:          acpi*:HISI00B1:*
alias:          of:N*T*Chisilicon,hns-dsaf-v2C*
alias:          of:N*T*Chisilicon,hns-dsaf-v2
alias:          of:N*T*Chisilicon,hns-dsaf-v1C*
alias:          of:N*T*Chisilicon,hns-dsaf-v1
