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.

Adds pci/pci-xlr.c to support for XLR PCI/PCI-X interface and XLS PCIe
interface.
Update irq.c to ack PCI interrupts, use irq handler data to do the
PCI/PCIe bus ack.

PCI support for the Fuloong 2E and Lemote Loongson 2F family machines is
mostly identical with the exception of CS5536 support.
Rename ops-fuloong2e.c to ops-loongson2.c then add the CS5536 support to
share most of the source code among Loongson machines.

The built-in Loongson 2E/2F northbridge in is bonito64-compatible but not
identical with it. To avoid influencing the original bonito64 support and
make the loongson support more maintainable, it's better to separate the
Bonito64 code from the Loongson code.
This also prepares the kernel for the coming Loongson 2f machines family
support.

To make source code of loongson sharable to the machines(such as gdium)
made by the other companies, we rename arch/mips/lemote to
arch/mips/loongson, asm/mach-lemote to asm/mach-loongson, and rename lm2e
to the name of the machine: fuloong-2e. accordingly, FULONG are renamed to
FULOONG2E to make it distinguishable to the future FULOONG2F. and also,
some other relative tuning is needed.

Also fix some build problems on CONFIG_PCI=n.

and PCI66 support is available for all TX49 boards.
