There's been a check for CONFIG_XILINX_CONSOLE since v2.6.30. But the
Kconfig symbol XILINX_CONSOLE was never added. Remove this check.

And, since DUMMY_CONSOLE depends on VT, we can now drop the check for
CONFIG_VT.

No reason to setup empty function. Core is checking
if this function should be called or not.

PCI_DRAM_OFFSET/pci_dram_offset is 0 all the time and there
is no difference for PCI and !PCI cases.
Also remove the whole code which setup archdata.dma_data
which is completely unused.

Return Microblaze default dma operations
and remove bus notifier which setups the same dma operations
by default when device is added to the system.

Both powerpc and microblaze have the same FDT blob in debugfs feature.
Move this to common location and remove the powerpc and microblaze
implementations. This feature could become more useful when FDT
overlay support is added.

This changes the path of the blob from "$arch/flat-device-tree" to
"device-tree/flat-device-tree".

Make of_get_flat_dt_prop arguments compatible with libfdt fdt_getprop
call in preparation to convert FDT code to use libfdt. Make the return
value const and the property length ptr type an int.
