libpayload: Provide selfboot function.

The calling convention of payload entry function is different by architecture.
    For example, X86 takes no arguments and ARM needs first param to be a
    cb_header_ptr*.

To help payloads load and execute other payloads easily and correctly, we should
    provide the selfboot() function in libpayload, using same prototype as defined
    in coreboot environment.
