Due to an unfortunate mistake the macro function actually checks the IP-core version instead of the IP-core version type which isn't what originally implied. Fix it by introducing a new helper __dw_pcie_ver_type_cmp() with the same semantic as the __dw_pcie_ver_cmp() counterpart except it refers to the dw_pcie.type field in order to perform the passed comparison operation.
