The Lantiq family of SoCs have a EBU (External Bus Unit). This patch adds
the driver that allows us to use the EBU as a PCI controller. In order for
PCI to work the EBU is set to endianess swap all the data. In addition we
need to make use of SWAP_IO_SPACE for device->host DMA to work.The clock of the PCI works in several modes (internal/external). If this
is not configured correctly the SoC will hang.Signed-off-by: John Crispin
