[PATCH] i2c: Reuse name strings in i2c bus drivers

Clean up name string usage in 12 i2c bus drivers:
* Use the i2c_adapter name for requesting the I/O region rather than
  redefining a new string.
* Do not initialize the i2c_adapter name to "unset".
This should save a few data bytes here and there.
