Two drivers already implement custom debugfs handling for their
i2c_adapter and more will come. So, let the core create a debugfs
directory per adapter and pass that to drivers for their debugfs files.
Convert the two existing users as well. Tested on a Renesas Lager board
with the i2c-gpio driver. npcm7xx still needs testing.

Looking forward to comments.
