Subject: [PATCH 2/2] rtc: max77802: Report platform modalias to fix module autoload

If the rtc-max77802 driver is built as a module, modalias information is
not filled so the module is not autoloaded. Use the MODULE_DEVICE_TABLE()
macro to export the platform ID table so the module contains that data.
