This patch series enables SoC-specific timer drivers to be built as 
loadable modules for Generic Kernel Image (GKI). SoC-specific timer 
drivers provide always-on broadcast timers that complement the ARM 
architectural timer.

This series is based on the previous MediaTek timer modularization work:

The series includes:
1. Export necessary functions from clocksource/mmio
2. Remove __init markings from timer-of to support modules
3. Convert MediaTek timer driver to support module build
4. Convert i.MX TPM timer driver to support module build

Testing performed:
- Built and tested on i.MX8ULP platform
- Built and tested on MediaTek platform
- Verified both built-in and module configurations
- Confirmed timer functionality in both configurations

Changes in v4:
- Refined the cover letter introduction to clarify that SoC-specific
  timers act as always-on broadcast timers complementing the ARM
  architectural timer.
- Expanded "GKI" to "Generic Kernel Image (GKI)" in commit messages.
- No functional changes to the code.

Changes in v3:
- Reworded summary line for timer-mediatek driver as suggested.
- Improved commit message formatting (line wrapping).
- No functional changes to the code.

Changes in v2:
- Added Signed-off-by from submitter (Zhipeng Wang) to all patches
  as requested by reviewers

Changes in v1:
- Fixed 'unsigned' to 'unsigned int' in clocksource_mmio_init()
- Changed MODULE_LICENSE from "GPL v2" to "GPL" for mediatek driver
- Added i.MX TPM timer driver module support
