ipq8064: prepare include files before adding UART driver

These patch modifies .h files to match the coreboot API. A few more
significant changes are:

 - UART specific fields removed from common board structure in cdp.h.
   These fields are set at compile time in u-boot (where this
   structure comes from), they will be set in a different structure in
   the UART driver in an upcoming patch.

 - an inline wrapper is added in gpio.h to provide GPIO API the UART
   driver expects.

 - the ipq_configure_gpio() is passed the descriptor placed in ro data.
