mb/facebook/monolith/devicetree: Use comma separated list for arrays

In order to improve the readability of the settings, use a comma
separated list to assign values to their indexes instead of repeating
the option name for each index.

Don't convert the settings for PCIe root ports as they will be moved
into the devicetree to their related root ports at some later point.

While on it, remove superfluous comments related to modified settings.
