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.
