Matti Vaittinen 21b02414f1 regulator: bd718x7: support ROHM BD71837 and BD71847 PMICs
BD71837 and BD71847 is PMIC intended for powering single-core,
dual-core, and quad-core SoC’s such as NXP-i.MX 8M. BD71847
is used for example on NXP imx8mm EVK.

Add regulator driver for ROHM BD71837 and BD71847 PMICs.
BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced
version containing 6 bucks and 6 LDOs. Voltages for DVS
bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted
when regulators are enabled. For other bucks and LDOs we may
have over- or undershooting if voltage is adjusted when
regulator is enabled. Thus this is prevented by default.

BD718x7 has a quirk which may leave power output disabled
after reset if enable/disable state was controlled by SW.
Thus the SW control is only allowed for BD71837  bucks
3 and 4 by default. The impact of this limitation must be
evaluated board-by board and restrictions may need to be
modified. (Linux driver get's these limitations from DT and we
may want to implement same on u-Boot driver).
