Subject: [PATCH v2 0/3] i2c: create debugfs entry per adapter

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 was tested using QEMU with the
quanta-gsj target.

Changes since v1:
* rebased to something close to 6.7-rc1 which includes i2c/for-mergewindow
* tested npcm7xx with QEMU
