regulator: ROHM bd7xxxx: Do not depend on parent driver data
The ROHM PMIC regulator drivers only need the regmap pointer from
the parent device. Regmap can be obtained via dev_get_regmap()
so do not require parent to populate driver data for that.

regulator: use linear_ranges helper
Change the regulator helpers to use common linear_ranges code.

regulator: bd71828: remove get_voltage operation
Simplify LDO6 voltage getting on BD71828 by removing the
get_voltage call-back and providing the fixed voltage in
regulator_desc instead

regulator: bd71828: Basic support for ROHM bd71828 PMIC regulators
ROHM BD71828 is a power management IC containing 7 bucks and 7 LDOs. Bucks
1,2,6 and 7 can be assigned to a regulator group controlled by run-levels.
Eg. Voltages and enable/disable statuses for specific run-levels (run0 to
run3) can be set via register interface and run level changes can then be
done either via I2C or GPIO.

This initial commit does not support assigning bucks to be controlled via
run-levels but only allows them to be individually controlled.

LDO5 voltage can also be controlled by GPIO2 pin and register interfaces
but this driver only supports the control via register.
