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/qualcomm/emac/qcom-emac.ko | grep alias
alias: platform:qcom-emac

After this patch:

$ modinfo drivers/net/ethernet/qualcomm/emac/qcom-emac.ko | grep alias
alias: platform:qcom-emac
alias: of:N*T*Cqcom,fsm9900-emacC*
alias: of:N*T*Cqcom,fsm9900-emac
