PCI: Move DesignWare IP support to new drivers/pci/dwc/ directory



Group all the PCI drivers that use DesignWare core in dwc directory.
dwc IP is capable of operating in both host mode and device mode and
keeping it inside the *host* directory is misleading.

# The following drivers are for devices that use the generic ACPI
# pci_root.c driver but don't support standard ECAM config access.
# They contain MCFG quirks to replace the generic ECAM accessors with
# device-specific ones that are shared with the DT driver.
# The ACPI driver is generic and should not require driver-specific
# config options to be enabled, so we always build these drivers on
# ARM64 and use internal ifdefs to only build the pieces we need
# depending on whether ACPI, the DT driver, or both are enabled.
