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/
max_microvolts
