RockPi support

[shawaj]

We need to enable RockPi support ASAP.

Requires:
#96
#88

Also we don't seem to have GPIO support for RockPi currently.

Here is an example device:

Acceptance criteria

• Add documentation
• ECC issue: https://nebraltd.slack.com/archives/C024BNQ1Y6T/p1638294078420000

	def detect_ecc(diagnostics):
	# The order of the values in the lists is important!
	# It determines which value will be available for which key
	commands = [
	'i2cdetect -y 1'

	parameters = ["60 --"]
	keys = ["ECC"]
	for (command, param, key) in zip(commands, parameters, keys):

this is currently outputting gateway_mfr test --path /dev/i2c-7 but it needs to be gateway_mfr --path /dev/i2c-7 test
