Thus further variable usage in the framework of the PCIE_PORT_LINK_CONTROL register initialization must imply the variable re-initialization. Alas it hasn't been taken into account in the commit ec7b952f453c ("PCI: dwc: Always enable CDM check if "snps,enable-cdm-check" exists"). Due to that the PCIE_PORT_LINK_CONTROL register will be written with improper value in case if the CDM-check is enabled. Let's fix this by re-initializing the 'val' variable with the PCIE_PORT_LINK_CONTROL CSR content before link-mode initialization.

Moreover enabling that feature saves 0.5 seconds of bootup time if no any device attached to the PCIe root port. It's a significant performance gain seeing the total bootup time takes about 3 seconds.

Since the DT-bindings of the Toshibo Visconti PCIe Host controller is fully compatible with the generic names set let's convert the driver to using that infrastructure. It won't take much effort since the low-level device driver implies the resources request only with no additional manipulations involving them. So just drop the locally defined clocks request procedures, activate the generic resources request capability and make sure the mandatory resources have been requested by the DW PCIe core driver.

Let's do that by adding the maintained files wildcard pattern like snps,dw-pcie*.yaml, which is applicable for all the old DW PCIe DT-schema files and the new one.
