chip/it83xx: introduction of IT83202/BX version
- Changing PLL and standby instruction didn't work on AX have been fixed on this version, so we can remove patches dedicated for AX. - Enable more chip config option. - Disable IT83XX_INTC_GROUP_21_22_SUPPORT option: Because IT8xxx2 series has its own interrupt group 21 and 22, so we will create another CL to support them. - System triggers a soft reset by default if IT83XX_ETWD_HW_RESET_SUPPORT option is enabled.
