The bd71828 includes the legacy header <linux/gpio.h> for no
reason, drop the include. The documentation mentions GPIO but there
is no usage of the GPIO namespace.

This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS
for drivers that existed in 4.14") but changes regulators didn't exist
in Linux 5.4 but did exist in Linux 5.10.

The dev_err_probe() has (at least) following benefits over dev_err()
when printing an error print for a failed function call at a device
driver probe:
- Omit error level print if error is 'EPRBE_DEFER'
- Standardized print format for returned error
- return the error value allowing shortening calls like:
if (ret) {
dev_err(...);
return ret;
}
to
if (ret)
return dev_err_probe(...);
Convert the ROHM BD71828, ROHM BD71815 and ROHM BD9576 regulator drivers
to use the dev_err_probe() when returned error is not hard-coded constant.

Use generic regamp ramp-delay helper function instead of implementing own.

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.

Simplify LDO6 voltage getting on BD71828 by removing the
get_voltage call-back and providing the fixed voltage in
regulator_desc instead

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.
