i2c: Remove the algorithm drivers from the config menu

The algorithm drivers are helper drivers that are selected automatically
as needed. There's no point in listing them in the config menu, it can
only confuse users and waste their time.

-	help
-	  This allows you to use a range of I2C adapters called bit-banging
-	  adapters.  Say Y if you own an I2C adapter belonging to this class
-	  and then say Y to the specific driver for you adapter below.
-
-	  This support is also available as a module.  If so, the module 
-	  will be called i2c-algo-bit.
