dt-bindings: pinctrl: spacemit: add syscon property

Browse source

In order to access the protected IO power domain registers, a valid
unlock sequence must be performed by writing the required keys to the
AIB Secure Access Register (ASAR).

The ASAR register resides within the APBC register address space.
A corresponding syscon property is added to allow the pinctrl driver
to access this register.
