Subject: [PATCH] spi: meson: Fix module autoload for OF platform driver

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

Hello,

This patch adds the missing MODULE_DEVICE_TABLE() for OF to export
that information so modules have the correct aliases built-in and
autoloading works correctly.

A longer explanation by Javier Canillas can be found here:

Thanks,
Luis
