[PATCH v1 7/9] common/iavf: add RefSync support

[Soumyadeep Hore <soumyadeep.hore@intel.com>]

From: Julian Grajkowski <julianx.grajkowski@intel.com>

Update virtchnl to reflect RefSync implementation.
Reading and modifying DPLL input pin configuration, including
Esync/RefSync option, is possible on VM using sysfs. The request
is passed from the VM via virtchnl message to the host driver
and results in an admin command being sent to FW. Before the
change only Esync enable/disable option was supported and it
used bit 6, but this change introduces support for RefSync option,
so there are now 3 possible values - Esync disabled (0), Esync
enabled (1) and RefSync enabled (2). The change updates description
of relevant virtchnl messages, but leaves the previous description
of bit 6 for backward compatibility, so that when RefSync is not
supported this bit may still be used for Esync enable/disable only.
