Update extcon next for v6.7

Detailed description for this pull request:
 - Add new Realtek DHC(Digital Home Hub) RTD SoC external connector driver
 : Detect USB Type C cable detection for USB and USB_HOST cable
   and support USB Type-C connector class. The extcon-rtk-type-c.c driver
   supports the following Realtek RTD SoC:
   - realtek,rtd1295-type-c
   - realtek,rtd1312c-type-c
   - realtek,rtd1315e-type-c
   - realtek,rtd1319-type-c
   - realtek,rtd1319d-type-c
   - realtek,rtd1395-type-c
   - realtek,rtd1619-type-c
   - realtek,rtd1619b-type-c
 
 - Add device-tree compatible string for extcon-max77693 and extcon-77843.c.
