Subject: [PATCH] PCI: intel-gw: Drop manual DW PCIe controller version setup
Since the DW PCIe common code (dw_pcie_version_detect()) now reads the IP
core version directly from the hardware, there is no point manually setting
the version for controllers newer than v4.70a.
Remove the now-superfluous intel-gw code that sets struct dw_pcie.version.
