dt-bindings: watchdog: aspeed,ast2400-wdt: Add support for AST2700

Add support for the AST2700 SoC in the ASPEED watchdog device tree
bindings. This includes:

- Adding "aspeed,ast2700-wdt" to the compatible string list.
- Extending the "aspeed,reset-mask" property description for AST2700.
- Defining AST2700-specific reset mask bits in aspeed-wdt.h,
  covering RESET1 to RESET5.
