regulator: bd71815: fix ramp values
Ramp values are inverted. This caused wrong values written to register
when ramp values were defined in device tree.

Invert values in table to fix this.

regulator: bd71815: Drop useless header
The bd71815 regulator driver includes the legacy header
<linux/gpio.h> for no reason, it is already using the proper
<linux/gpio/consumer.h> include. Drop the include.

regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers between 5.10 and 5.15
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 5.10 but did exist in Linux 5.15.

regulator: Use of_property_present() for testing DT property presence
It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

regulator: bd71815: bd71828: bd9576: Use dev_err_probe()
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.

regulator: bd71815: switch to using devm_fwnode_gpiod_get()
I would like to stop exporting OF-specific devm_gpiod_get_from_of_node()
so that gpiolib can be cleaned a bit, so let's switch to the generic
fwnode property API.

regulator: bd71815: Get rid of struct bd71815_pmic
The content of bd71815_regulators is never changed, no need to duplicate
it, thus remove descs[BD71815_REGULATOR_CNT].
The *regmap, *dev and *rdev[BD71815_REGULATOR_CNT] are not really needed.
The *gps is unused.

Thus the struct bd71815_pmic can be removed.

1aad39001e regulator: Support ROHM BD71815 regulators
Support voltage control for regulators on ROHM BD71815 PMIC.

ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED).
Bucks 1 and 2 support HW state based voltage level and enable states. Other
regulators support HW state based enable states. All bucks and LDOs 1-5
allow voltage changes for RUN state and LDO4 can be enabled/disabled via
GPIO.

LDO3 does support changing between two predetermined voltages by using
a GPIO but this functionality is not included in this commit.

This work is derived from driver originally written by Tony Luo
<luofc@embedinfo.com> - although not much of original work is left.
