[PATCH 2/3] watchdog: mediatek: add MT7629 reset controller support

[Chuanhong Guo]

MT7629 currently matches the MT6589 fallback, which exposes reset IDs
0 through 11. The MT7629 CONN_MCU reset is at bit 12 of the SWSYSRST
register and cannot be requested through this fallback.

Add MT7629 match data with 13 reset IDs to cover the CONN_MCU reset.
