The way I had expected this to work was that TIMER_OF_DECLARE_PDEV()
always registers the platform_driver and just skips the
section magic when it's in a loadable module.

Yes it would be a nice change, but it seems to be not possible for the 
early + builtin + module combination we have AFAICS.

What about to have two macros:

/*
  * Declares module_platform_driver
  * Assigns __driver.driver.of_match_table = __of_match
  * Assigns __driver.driver.name = __name
  */
TIMER_OF_DECLARE_PLATFORM_DRIVER(__name, __driver, __of_match)

/*
  * Does the same as the above but if MODULE is not set then then we
  * end up with timer-probe() instead of builtin_platform_driver
  */
TIMER_OF_DECLARE_EARLY_PLATFORM_DRIVER(__name, __driver, __of_match)

So when someone is converting a driver into a module, it can change the 
driver to use these macros instead.
