[Xen-changelog] [qemu-xen-unstable] hw/piix4acpi.c: cleanup logging



commit f2e0a24d00b2f0c591719bab088fbe3654955066
Author: Ian Jackson <ian.jackson@xxxxxxxxxxxxx>

    hw/piix4acpi.c: cleanup logging
    
    this is a simple cleanup patch for logging in piix4acpi: it replaces all
    the calls to fprintf with calls to a specific logging function that has
    3 simple logging levels.
