[U-Boot] U-Boot DWC2 unused variables

[Stephen Warren]

Oleksandr,

Thanks for the quick response on the s-o-b lines. Another question: The
compiler is complaining about hprt0 being written but then not used in
the functions below. I assume the second parameter passed to
dwc_write_reg32() should be hprt0.d32 rather than val?
