OF interface provides to read the u32 value via standard interface
of_property_read_u32(). Use this API to read "regulator-min-microvolts"
and "regulator-max-microvolt".
This will make consistent with other property value reads.

Pull regulator updates from Mark Brown:
"Aside from a fix for a spurious warning (which caused more problems
than it fixed in the fixing really) this is all driver updates,
including new drivers for Dialog PV88060/90 and TI LM363x and TPS65086
devices. The qcom_smd driver has had PM8916 and PMA8084 support
added"

Originally queue_delayed_work() used to negative error codes or 0 and 1
on success depending if the work was queued or not. It caused a lot of
bugs where people treated all non-zero returns as failures so we changed
it to return bool instead in d4283e9378 ('workqueue: make queueing
functions return bool'). Now it never returns failure.
Checking for negative values causes a static checker warning since it is
impossible based on the bool type.

The lp872x structure holds a reference to the DVS GPIO, but it is never actually
used anywhere, since a first reference exists from the lp872x_dvs structure.

In order to select the regulators via of_find_regulator_by_node (and thus use
them in devicetree), defining of_match for each regulator is required.

The enable/disable values for GPIO LDOs are reversed. It seems no one
noticed as AXP22x support was introduced recently, and no one was using
the GPIO LDOs, either because no designs actually use them or board
support hasn't caught up.

This regulator is on a slow i2c bus. Register accesses are very simple,
they all either enable/disable a regulator channel, or select a new
voltage level. Thus, reading registers from the device will always
return what was last written.
Therefore we can save a lot of time when reading registers by using a
regmap_cache. Since the register map is relatively large, but we only
ever access a few of them, we use an RBTREE cache.

set/get_bypass ops were missing for ldo1/ldo2 on tps65917 and
ldo9 on palmas/tps659038 which support bypass mode.
Adding the bypass ops helps consumers configure these ldos in
bypass mode or remove bypass mode if need be.

These were supposed to be bitwise AND instead of logical. Also kernel
style is for the operator to be on the first line and I removed some
extra parenthesis.
