    LinuxKPI: acpi: fix guid_t argument type
    
    acpi_check_dsm() and acpi_evaluate_dsm_typed() take a guid_t argument
    and not a char *.  For in-tree Linux based drivers this leads to a
    compile error due to a warning.  Fix the function argument type and
    cast internally.
    
    While this made the long statements in the wrapper functions for *_dsm_*
    even less readable split them up using a local variable.
