Add a shell to interact with I2C devices. Currently scanning for devices
is supported. Example output:
uart:~$ i2c scan I2C_1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- 18 -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: 40 -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
2 devices found on I2C_1
uart:~$ i2c scan I2C_3
i2c - I2C commands
Subcommands:
I2C_1 :I2C_1

This shell is based on the a sample that did the same thing and was
limited in support. The sample is now removed in favour of this generic
shell module.
