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.

Fixes: 0b0a780d52ad ("PCI: dwc: Add macros to compare Synopsys IP core versions")
