dmaengine: ste_dma40: Also report the number of logical channels

Now we know the total of physical and logical channels, we may as
well report them within the information log.

Before:
dma40 dma40.0: hardware revision: 3 @ 0x801c0000 with 8 physical channels

After:
<as above ...> and 256 logical channels
