[PATCH V6 07/11] soc: mediatek: PMIC wrap: move wdt_src into the pmic_wrapper_type struct

John Crispin blogic at openwrt.org

Different SoCs will use different bitmask for the wdt_src. This patch
defines the bitmask in the pmic_wrapper_type struct. This allows us to
support new SoCs with a different bitmask to the one currently used.
