This adds YAML device tree bindings for the Integrator/AP
logic modules. These are plug-in tiles used typically for
FPGA prototyping.

ChangeLog v2->v3:
- Put proper ranges around the addresses managed by the
LM bus, 0xc0000000-0xffffffff as
<0xc0000000 0xc0000000 0x40000000>
- Put unit name on the first LM bus bus@c0000000 in the
example in the bindings.
- Drop leading zeroes in the unit names of the devices
in the example.
ChangeLog v1->v2:
- Fix Logical->Logic spelling error
- Set generic names for bus and serial
- Just map the addresses 1:1 and use empty ranges, as the
LM's don't really translate the address.
- Provide proper DMA ranges: the LM modules see the RAM at
the system-wide alias @80000000 rather than 1:1.
- Drop the reg from the bus node (we just need the ranges)
- Make the regexp for the bus node such that @address is
optional, as we don't require any reg on the node
