[PATCH v2 7/7] regulator: tps6594-regulator: Add TI TPS652G1 PMIC regulators

[Michael Walle <mwalle@kernel.org>]

The TI TPS652G1 is a stripped down version of the TPS65224 PMIC. It
doesn't feature the multiphase buck converter nor any voltage
monitoring. Due to the latter there are no interrupts serviced. In case
of the TPS652G1 any interrupt related setup is just skipped.
