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/input/misc/da9063_onkey.ko | grep alias
alias:          platform:da9063-onkey

After this patch:

$ modinfo drivers/input/misc/da9063_onkey.ko | grep alias
alias:          platform:da9063-onkey
alias:          of:N*T*Cdlg,da9062-onkeyC*
alias:          of:N*T*Cdlg,da9062-onkey
alias:          of:N*T*Cdlg,da9063-onkeyC*
alias:          of:N*T*Cdlg,da9063-onkey
