[PATCH v11 08/37] dt-bindings: pinctrl: airoha: an7583: allow configuration of non-gpio default pins as gpio and pwm

Some AN7583 pins have non-gpio default settings. This patch provides a way
to configure such pins as GPIO or PWM. Also add gpio-range property in the
dts example.

Please note that gpio52 pin can't be configured as PWM pin.
