Get I2C adapter driver names from sysfs. The old method (matching against

Browse Source 
regexp for known I2C adapters) is still used as a fallback, as early 2.6
kernels don't support the new method, and some drivers (i2c-viapro for
example) do not bind to their device so the new method doesn't work for
them.
