If the boot firmware does not support ACPI we need a way to pass device
configuration information to the drivers. The unified device properties API
already supports passing platform data via properties so let's take
advantage of that and allow probe drivers to pass set of properties to the
host controller driver.
In order to do that we need to be able to modify the MFD cell corresponding
the host controller, so make the core driver to take copy of the cell
instead of using it directly. Then we can assign info->pset to the
resulting copy of a cell and let the MFD core to assign that to the
resulting device.

Jim Davis reported the compilation error with a random configuration which
apparently has CONFIG_PM=y and CONFIG_PM_SLEEP=n. With that conditions we have
missed definition of INTEL_LPSS_SLEEP_PM_OPS macro. Add it here.

The new coming Intel platforms such as Skylake will contain Sunrisepoint PCH.
The main difference to the previous platforms is that the LPSS devices are
compound devices where usually main (SPI, HSUART, or I2C) and DMA IPs are
present.
This patch brings the driver for such devices found on Sunrisepoint PCH.
