This patch adds support for QSR1000/QSR2000 family of chipsets to qtnfmac_pcie platform driver. QSR1000/QSR2000 (aka Topaz) is a family of 80MHz, 11ac Wave2, 4x4/2x4/2x2 chips, including single and dual band devices. Depending on specific chip model and firmware in use, either STA or both STA and AP modes are supported. Patch adds Topaz support to qtnfmac_pcie driver. Proper platform bus will be selected on probing based on chip ID.
