From: Chunyan Zhang <chunyan.zhang@xxxxxxxxxx>

This patchset was based on the previous one [1], and add a
boilerplate macro for module build purpose according to comments
from Thomas Gleixner on the patch [2].

Also switch sprd timer driver to use the help macro to support
module build.

* Changes from v2:
- Define one macro TIMER_PLATFORM_DECLEAR() to replace the three ones in the v2;
- Use builtin_platform_driver() to replace module_platform_driver() to make sure
unloading timer modules not supported;
- Add more description to explain that unloading is not supported.

* Changes from v1:
- Removed TIMER_OF_DECLARE() from timer-sprd.c, and removed ifdef;
- Rebased on v5.14-rc1.
