No functional, change, but some improvements:
- Declare set_gpio() as static (only called locally)
- Handle the type ('open-drain') property independently from the
mode one.
- Replace mmio_clrbits_32() + mmio_setbits_32() with
mmio_clrsetbits_32().
- Add a missing log
- Add missing U() in macro definitions
