306456c21c mfd: bd70528: Drop BD70528 support
The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.

regulator: rohm-generic: remove unused dummies
Function rohm_regulator_set_voltage_sel_restricted() and
rohm_regulator_set_dvs_levels() had inlined dummy implementations for
cases when the real implementation was not configured in.

All of the drivers who issue the call to these functions do SELECT the
real implementation from the Kconfig. There should be no cases where the
real implementation was not selected by the drivers using these
functions - such a situation is likely to be an error which deserves to be
noticed at compile-time.

These dummies could in theory be used for compile-testing the drivers
only (without the generic rohm regulator pieces). However, for such
compile testing we should manually drop the selection from KConfig - and
I guess that if it does not work out-of-the-box, then it is not going to
happen. Especially when there should be no reason to omit
compile-testing the generic rohm_regulator part.

Crash test dummies.

c294554111
regulator: bd718x7, bd71828, Fix dvs voltage levels
The ROHM BD718x7 and BD71828 drivers support setting HW state
specific voltages from device-tree. This is used also by various
in-tree DTS files.

These drivers do incorrectly try to compose bit-map using enum
values. By a chance this works for first two valid levels having
values 1 and 2 - but setting values for the rest of the levels
do indicate capability of setting values for first levels as
well. Luckily the regulators which support setting values for
SUSPEND/LPSR do usually also support setting values for RUN
and IDLE too - thus this has not been such a fatal issue.

Fix this by defining the old enum values as bits and fixing the
parsing code. This allows keeping existing IC specific drivers
intact and only slightly changing the rohm-regulator.c

Do device matching using the platform_device_id instead of using
