Subject: [PATCH v1 2/2] hwmon: (aspeed-g6-pwm-tach): Add AST2700 compatible string

Extends device tree support to include the AST2700 chip variant by
adding its compatible string to the device match table.

The AST2700 PWM/TACH hardware is compatible with the existing driver
implementation used for AST2600.
