[PATCH v2 0/2] i2c: Don't assume bus nr 0 if none was specified

[Karol Lewandowski]

Changes since v1:
 - Dropped reduntant i2c-octeon change

i2c controller drivers used to assume bus number 0 when none (-1) was
specified.

This worked on non-device tree systems, where one could explicitly
specify bus number via platform data.  On DT-enabled systems bus
number is always -1.

This patchset reworks few remaining drivers to use dynamic bus
allocation when no id has been provided.

[ I've found out this when I've tried to instantiate more than one
  i2c-gpio instance on DT-enabled system. I've, hopefully, fixed few
  other drivers too. ]
