Subject: [PATCH] wil6210: set platform features based on FW capabilities
Git-commit: 594b59ec70e14f9cdb901f9e2c7c6a771c6231fa
Patch-mainline: v4.16-rc1
References: FATE#326906
In some cases the platform should be aware of the FW capabilities
to decide which feature to enable.
For example, FW can control the external REF clock for power saving.
Driver should notify the platform about that, to allow platform
power management optimization.
