Merge series "Enable VBUS current boost on pm8150b platforms" from Bryan O'Donoghue <bryan.odonoghue@linaro.org>:

V3:
- Drop the SoC regulator constraints for
  regulator-min-microamp
  regulator-max-microamp
  These will be applied on a per-board basis - Mark Brown

V2:
The first version of this patch set the current limit to 3 amps as was done
in downstream. Mark indicated a preference to set this on a per-system
basis instead of blitzing it, as in downstream.

Looking at what was upstream versus what was in my working tree I saw that
in fact the VBUS boost driver had been upstreamed minus accompanying DTS in
pm8150b.

So there's no need for a fixes as this driver doesn't appear to be in use.
A subsequent patchset will enable the VBUS boost for the two relevant
upstream platforms.

First thing though, is the driver + dts change.

- Use regulator_set_current_limit_regmap/regulator_get_current_limit_regmap
  with a relevant current-to-bitmap lookup.

- Add a parallel DTS entry to the pm8150b
  It looks like this was submitted upstream but not followed up on

  I've add regulator-min-microamp/regulator-max-microamp to Wesley's
  original work.

I've made sure to test that its possible to set the current to anything in
the range of 500 mA to 3 A and confirmed the output on a scope.

Once these two patches are in, I'll send out board enablement for the
sm8150-mtp and qrb5165-rb5.
