At the context with *rdev, use rdev_get_drvdata() is more intuitive.

Merge tag 'for-5.14-regulator' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into regulator-5.14
regulator: Changes for v5.14-rc1
This adds regulator_sync_voltage_rdev(), which is used as a dependency
for new Tegra power domain code.
According to the datasheet:
REGISTER DETAILS − 0x02 BUCK, BUCK_OUT is BIT0 ~ BIT7.
So vsel_mask for FAN53880_BUCK should be 0xFF.

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.

The MT6359_BUCK and MT6359_LDO_LINEAR macros setup both
linear settings (min_uV, uV_step, linear_min_sel) and linar_range
(linear_ranges, n_linear_ranges) settings.
All the linear range tables actually only has one entry.
Let's simplify it by using linear instead of linear range.
The linear_min_sel setting is 0 for all cases, remove it
from the macros.

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.

in this case we need to restore the coupled voltages to the state that is
suitable for hardware during boot. Add new regulator_sync_voltage_rdev()
