[PATCH v6 3/6] commands: add i2c commands

[Eric Bénard]

theses commands allow low level access to i2c bus and can be useful
to setup an i2c device without having to add code, compile and flash
barebox.

Signed-off-by: Eric Bénard <eric@eukrea.com>
---
v6 :
	add log before exiting when i2c bus doesn't exist
v5 :
	updated as per Marc's comments
	better error handling in write
	better default bus handling in read & write
v4 :
	updated as per Sascha and Marc's comments
	use bus 0 as a default for i2c_read & write
	replace malloc with xmalloc
	fix simple_strtol configuration for parameters
v3 : 
	enable brain and fix v2
	tested on iMX27
v2 :
	updated as per Sascha's comments
