Commit 3fca3d3d5075 ("platform-x86: intel_mid_thermal: add msic_thermal
alias") added a "msic_thermal" entry to the driver's platform device ID
table since that was the platform dev name registered in some platforms
and the only dev in the platform table was "msic_sensor" (DRIVER_NAME).

But then commit 634830704d80 ("x86/mid/thermal: Add msic_thermal alias")
changed DRIVER_NAME from "msic_sensor" to "msic_thermal", and so there's
now duplicated entries in the platform device ID table.

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/platform/x86/intel_mid_thermal.ko | grep alias
$

After this patch:

$ modinfo drivers/platform/x86/intel_mid_thermal.ko | grep alias
alias:          platform:msic_thermal

Both patches pushed to testing.
