[media] rc: meson-ir: Fix module autoload

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/media/rc/meson-ir.ko | grep alias
$

After this patch:

$ modinfo drivers/media/rc/meson-ir.ko | grep alias
alias:          of:N*T*Camlogic,meson-gxbb-irC*
alias:          of:N*T*Camlogic,meson-gxbb-ir
alias:          of:N*T*Camlogic,meson8b-irC*
alias:          of:N*T*Camlogic,meson8b-ir
alias:          of:N*T*Camlogic,meson6-irC*
alias:          of:N*T*Camlogic,meson6-ir
