dt-bindings: bus: Remove unused bindings
As stated in [1] the Baikal platforms are not supported and the respective driver code has just been removed. Remove unused bindings.

Baikal-T1 CPU or DMAC MMIO requests are handled by the AMBA 3 AXI Interconnect
|
||||
which routes them to the AXI-APB bridge. This interface is a single master
|
||||
multiple slaves bus in turn serializing IO accesses and routing them to the
|
||||
addressed APB slave devices. In case of any APB protocol collisions, slave
|
||||
device not responding on timeout an IRQ is raised with an erroneous address
|
||||
reported to the APB terminator (APB Errors Handler Block).

AXI3-bus is the main communication bus of Baikal-T1 SoC connecting all
|
||||
high-speed peripheral IP-cores with RAM controller and with MIPS P5600
|
||||
cores. Traffic arbitration is done by means of DW AXI Interconnect (so
|
||||
called AXI Main Interconnect) routing IO requests from one block to
|
||||
another: from CPU to SoC peripherals and between some SoC peripherals
|
||||
(mostly between peripheral devices and RAM, but also between DMA and
|
||||
some peripherals). In case of any protocol error, device not responding
|
||||
an IRQ is raised and a faulty situation is reported to the AXI EHB
|
||||
(Errors Handler Block) embedded on top of the DW AXI Interconnect and
|
||||
accessible by means of the Baikal-T1 System Controller.
