regulator: tps65219: use generic set_bypass()
Due to wrong interpretation of the specification,
custom implementation was used instead of standard regmap helper.
LINK: https://lore.kernel.org/all/c2014039-f1e8-6976-33d6-52e2dd4e7b66@baylibre.com/
Fixes: c12ac5fc3e0a ("regulator: drivers: Add TI TPS65219 PMIC regulators support")
Regulator does NOT require to be off to be switched to bypass mode.
