register 0x1fbf0234 will be used by pinctrl driver (I will post it soon) for
pwm muxing. The issue here is clock, pinctrl, gpio, pwm and (future) serdes
registers are all interleaved in a non-regular fashion in the following
IO space:
- <0x1fa20000 - 0x1fa20384>
- <0x1fb00000 - 0x1fb0096c>
- <0x1fbf0200 - 0x1fbf02bc>
So in order to avoid conflicts we need a sparse mapping.
