This was suggested by Mark Brown in response to a patch for adding
this functionality only for the s3c2410 bus:
  https://lkml.org/lkml/2012/11/20/681

I have also modified the i2c-pxa driver to use this new functionality.
As Haojian Zhuang has Acked this patch, I believe that this has now
been tested.

Reposting (with Haojian Zhuang's ack) in the hopes that a maintainer
will pick it up.  :)

  i2c-core: dt: Pick i2c bus number from i2c alias if present
  i2c: pxa: Use i2c-core to get bus number now
