spi: ath79: Fix 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/spi/spi-ath79.ko | grep alias
alias:          platform:ath79-spi

After this patch:

$ modinfo drivers/spi/spi-ath79.ko | grep alias
alias:          platform:ath79-spi
alias:          of:N*T*Cqca,ar7100-spiC*
alias:          of:N*T*Cqca,ar7100-spi
