  - Refine the definitions and parameters about CLK,
    AHB controller, SDRAM controller, Static memory controllers.
  - Add APB_CLK, AHB_CLK, SYS_CLK definitions for backward compatible.
  - ftahbc010:
    - Update include path of ftahbc010.
  - ftsdmc021:
    - Update include path of ftsdmc021.
  - ftsmc020:
    - Update include path of ftsmc020.
  - ftwdt010:
    - Fix WDT define and update include path.
    - Fix ftwdt010 for hardware reset.
  - ftpmu010:
    - Remove duplicate PMU definitions.
    - Add related configurations.
  - Fix MAX malloc len and fix saveenv.
  - clean up.
