Drop ROHM BD70528 support

Unfortunately there has not been a big demand for ROHM BD70528
IC. The few users I know control PMIC from separate M4-core,
which is not running Linux. I am not aware of any users of this
Linux driver.

While I did really like this IC and writing the drivers for it,
seems like these drivers are becoming useless burden. So, I see
no point in maintaining them. Let's just drop the drivers if
there is no objections to this series. :(

The regulator, WDG and power-supply drivers were already dropped.

The RTC and clk drivers remain in use by few other ROHM IC drivers.
Nevertheless, they are already converted to not depend the BD70528
defines during previous cycle.

This series cleans the remaining pieces, GPIO, MFD, dt-bindings and
MAINTAINER entries. The GPIO code uses defines from MFD - but the GPIO
part is also depending on MFD KConfig entry - so there should be no
breakages even if the patches were applied to respective subsystem trees
and were not carried via single tree.
