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.

This property configures the Aspeed watchdog timer's reset mask, which
controls which peripherals are reset when the watchdog timer expires.
Some platforms require that certain devices be left untouched across a
reboot; aspeed,reset-mask can now be used to express such constraints.
