regulator: Update for v4.5

Browse Source 
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.

Qualcomm Resource Power Manager (RPM) over SMD
QCOM SMD RPM REGULATOR
This driver is used to interface with the Resource Power Manager (RPM) found in
various Qualcomm platforms. The RPM allows each component in the system to vote
for state of the system resources, such as clocks, regulators and bus
frequencies.
The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
Because SMD is used as the communication transport mechanism, the RPM resides as
a subnode of the SMD. As such, the SMD-RPM regulator requires that the SMD and
RPM nodes be present.
