pinctrl: aspeed: Add implementation-related documentation The ASPEED pinctrl driver implementations make heavy use of macros to minimise tedium of implementation and maximise the chance that the compiler will catch errors in defining signal and pin configurations. While the goal of minimising errors is achieved, it is at the cost of the complexity of the macros. Document examples of the expanded form of pin declarations to demonstrate the operation of the macros.
