ftwdt010_wdt: move header to include/faraday and enhance

1. Move header to include/faraday
2. Fix include path in ftwdt010_wdt.c
3. Fix function prototype and declaration to
  - ftwdt010_wdt_settimeout
  - ftwdt010_wdt_reset
  - ftwdt010_wdt_disable
4. Add "#if definde (CONFIG_HW_WATCHDOG)" let user have flexibilty
