While it is vanishingly unlikely that the device will be deployed on other
architectures removing the dependency facilitates build testing when doing
generic work on both the MFD core for the device and the subsystem drivers.

There appears to be no actual code dependency.

Since we don't have a PWM API every PWM driver ends up exporting its
own version and we need to limit the platforms we try to build them on
in order to avoid multiple definitions. As the AB8500 is normally a
companion chip for the U8500 CPU depend on that architecture.

... and convert it to a dev_info print at probe time.

There are many variants of this chip with different values of VERSIONCRC.
The set of values is large, and not useful to enumerate. All are SW
compatible. The difference lies in default settings of the various power
rails, and other similar differences. The driver, or clients of the
driver, shouldn't be affected by this, since all rails should be
programmed into the desired state in all cases for correct operation.

Allow MFD cells to have pm_runtime_no_callbacks() called on them during
registration. This causes the runtime PM framework to ignore them,
allowing use of runtime PM to suspend the device as a whole even if
not all drivers for the MFD can usefully implement runtime PM. For
example, RTCs are likely to run continuously regardless of the power
state of the system.
