[PATCH v2 0/4] clocksource: Add module support for timer drivers

This patch series enables clocksource timer drivers to be built as
loadable kernel modules, which is particularly useful for GKI
(Generic Kernel Image) configurations.

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 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
