On some devices (TH 2.x devices at the moment), the internal time counter
is initially not synchronized to the global crystal clock, so the time
stamps it produces will not be useful. In this case, the driver needs
to force the time counter resync.
This applies the workaround to relevant devices.

Already during the subdevice initialization time, devices will need
to reference Intel TH controller descriptor structure.
This patch moves setting the drvdata from the pci glue to intel_th
core, before subdevices are populated.

This patch adds basic support for PCI-based Intel TH devices. It requests
2 bars (configuration registers for the subdevices and STH channel MMIO
region) and calls into Intel TH core code to create the bus with subdevices
etc.
