    Add console wrapper for UART driver
    
    Coreboot is designed to have a single serial console at most, on top
    of that it may have a CBMEM (virtual) console. Matters are complicated
    by the fact that console interface is different between bootblock and
    later stages.
    
    A linker list of console driver descriptors is used to allow to
    determine the set and type of console drivers at compile time. Even
    though the upstream seems to have done away with this approach, which
    does not seem the best idea.
    
    As an alternative this patch introduces a common wrapper which
    different UART drivers can plug in into. The driver exports a single
    API which can be used both directly (in bootblock) and through the
    wrapper (in later stages).
    
    The existing drivers can be adjusted to fit this scheme one by one.
    The common UART driver API also aligns fine with the upstream
    approach.
