    gcc47: Backport static initialization acceptance.
    
    I only backporting these so that failing to accept drm/i915 _MMIO() stuff
    would *not* be used as an argument to remove gcc47 alternative compiler
    from base, just because "oh look it does not compile the i915.ko".
    The gcc47 is likely the last C compiler compilable with C compiler able
    to bootstrap the c++ compiler that is used on x86_64 anymore.
    If anyone has/works on simple C compiler that could boostrap modern gcc,
    you know where I hanging out and I gladly replace gcc47 with it in base.
    
    It only takes few lines to accept updated drm/i915 "features".
    It still warns with -pedantic:
    /usr/src/sys/dev/drm/i915/intel_pm.c:3925:3: warning: initializer element is not constant [-pedantic]
    /usr/src/sys/dev/drm/i915/intel_pm.c:3925:3: warning: (near initialization for 'wm0_pipe_reg[0]') [-pedantic]
    /usr/src/sys/dev/drm/i915/intel_pm.c:3926:3: warning: initializer element is not constant [-pedantic]
    /usr/src/sys/dev/drm/i915/intel_pm.c:3926:3: warning: (near initialization for 'wm0_pipe_reg[1]') [-pedantic]
    /usr/src/sys/dev/drm/i915/intel_pm.c:3927:3: warning: initializer element is not constant [-pedantic]
    /usr/src/sys/dev/drm/i915/intel_pm.c:3927:3: warning: (near initialization for 'wm0_pipe_reg[2]') [-pedantic]
    ...
    So far i915 is the only place in kernel that does this, please lets keep it at this.
    
    Check C99 Standard: Section 6.7.8 for more info.
