Braswell: Implement Gpio library functions to read RAMID

Added GPIO library code to allow all BSW board specific code
    to use memory configuration GPIOs in GPIO Input mode and read
    them to determine which memory type is on the board.

Also added other GPIO related APIs to support GPIO access
    in BSW.
