Add support to instantiate LM90-compatible sensors from a device-tree
configuration.
When the kernel has device tree support, we avoid doing the auto-detection
as probing the busses might mess-up sensitive I2C devices or trigger long
timeouts on non-functional busses.

In order to support Wake-On-Lan when using the RK3288 integrated MAC
(with an external RGMII PHY), we need to avoid shutting down the regulator
of the external PHY when the MAC is suspended as it's currently done in the MAC
platform code.
As a first step, create independant callbacks for suspend/r
