regulator: tps65219: Fix matching interrupts for their regulators
The driver's probe() first registers regulators in a loop and then in a
second loop passes them as irq data to the interrupt handlers.  However
the function to get the regulator for given name
tps65219_get_rdev_by_name() was a no-op due to argument passed by value,
not pointer, thus the second loop assigned always same value - from
previous loop.  The interrupts, when fired, where executed with wrong
data.  Compiler also noticed it:

  drivers/regulator/tps65219-regulator.c: In function ‘tps65219_get_rdev_by_name’:
  drivers/regulator/tps65219-regulator.c:292:60: error: parameter ‘dev’ set but not used [-Werror=unused-but-set-parameter]

regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers between 5.15 and 6.1
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 5.15 but did exist in Linux 6.1.

regulator: tps65219: use generic set_bypass()
Due to wrong interpretation of the specification,
custom implementation was used instead of standard regmap helper.

Fixes: c12ac5fc3e ("regulator: drivers: Add TI TPS65219 PMIC regulators support")

Regulator does NOT require to be off to be switched to bypass mode.

regulator: tps65219: Fix is_enabled checking in tps65219_set_bypass
Testing .enable cannot tell if a regulator is enabled or not, check return
value of .is_enabled() instead.
Also remove unneeded ret variable.

regulator: tps65219: Fix .bypass_val_on setting
The .bypass_val_on setting does not match the .bypass_mask setting, so the
.bypass_mask bit will never get set.  Fix it by removing .bypass_val_on
setting, the regulator_set_bypass_regmap and regulator_get_bypass_regmap
helpers will use rdev->desc->bypass_mask as val_on if the val_on is 0.

regulator: drivers: Add TI TPS65219 PMIC regulators support
The regulators set consists of 3 bucks DCDCs and 4 LDOs. The output
voltages are configurable and are meant to supply power to the
main processor and other components.

Validation:
Visual check: cat /sys/kernel/debug/regulator/regulator_summary
Validation: userspace-consumer and virtual-regulator required
to test further

Enable/Disable:
cat /sys/devices/platform/userspace-consumer-VDDSHV_SD_IO_PMIC/state
echo disabled > /sys/devices/platform/
userspace-consumer-VDDSHV_SD_IO_PMIC/state
echo enabled > /sys/devices/platform/
userspace-consumer-VDDSHV_SD_IO_PMIC/state

Change voltage:
cat /sys/devices/platform/regulator-virtual-ldo1/min_microvolts
echo 1000000 > /sys/devices/platform/regulator-virtual-ldo1/
min_microvolts
echo 3000000 > /sys/devices/platform/regulator-virtual-ldo1/
