SMI clamp and reset operations should be implemented in SMI driver
instead of PM driver.

When we enable/disable power domain, the SMI LARBs linked to this power
domain could be affected by the bus glitch. To avoid this issue, SMI
need to apply clamp and reset opereations.

This patch mainly add these functions:
1) Add SMI reset controller driver to implement SMI LARBs reset opereations.
2) Add bindings for describing the reset controller.

Changes v2:
- According to previous discussions in v1, divided these four
  patches into two topic separately
- Change from 'mediatek,larb-rst-syscon' to 'mediatek,larb-rst'
- Modify the description for 'mediatek,larb-rst'
- Modify the description for '#reset-cells'
- Change compatible to 'mediatek,mt8188-smi-reset'
- Add COMPILE_TEST for RESET_MTK_SMI in Kconfig
- Drop label in binding's example
- Use MMIO instead of regmap in reset controller driver
