[PATCH v2 0/6] Add support of inverting power control and some minor cleanup

By default, dw_mmc outputs high level voltage to indicate powering
up the card and outputs low level vcltage to indicate powering
off the card. But that is not always correct. The power io should
be able to control different kind of hw components to supply or
cutoff power to the card. We have boards that need this patchset
to make the power control correct. Meanwhile let's expose it to
DT for board-specific usage.

Changes in v2:
- fix copy-paste err and typo
