Utilize the managed resource (devres) framework and add the following
devm_* helpers for the SPMI driver:
- devm_spmi_controller_alloc()
- devm_spmi_controller_add()
[sboyd@kernel.org: Rename to spmi-devres for module niceness, slap on
GPL module license]

Qualcomm's PMIC Arbiter SPMI controller functions as a bus master and
is used to communication with one or more PMIC (slave) devices on the
SPMI bus. The PMIC Arbiter is actually a hardware wrapper around the
SPMI controller that provides concurrent and autonomous PMIC access
to various entities that need to communicate with the PMIC.
The SPMI controller hardware handles all of the SPMI bus activity (bus
arbitration, sequence start condition, transmission of frames, etc).
This software driver uses the PMIC Arbiter register interface to
initiate command sequences on the SPMI bus. The status register is
read to determine when the command sequence has completed and whether
or not it completed successfully.

System Power Management Interface (SPMI) is a specification
developed by the MIPI (Mobile Industry Process Interface) Alliance
optimized for the real time control of Power Management ICs (PMIC).
SPMI is a two-wire serial interface that supports up to 4 master
devices and up to 16 logical slaves.
The framework supports message APIs, multiple busses (1 controller
per bus) and multiple clients/slave devices per controller.
