The anchors used in g3doc aren't in normal markdown or at least how
github renders it.  Remove them.

Also, split lines at 80 column width.

-Sys can get the total number of PCIe slots from BMC using this command. When BMC receives this command, BMC can enumerate over all the PCIe slots and create a hashmap with all the available PCIe slot name - I2C bus number mappings. BMC can then send the total number of PCIe slots as part of this command response.

-If Sys gets N total slots as part of the above command, then Sys can send this command N times with Entry IDs ranging from 0 to N - 1. Say, Sys sends this command with Entry ID as 1, BMC can go and fetch the first PCIe slot name - I2C bus number mapping from the hashmap created above and then send the PCIe slot name and I2C bus number as part of the command response.
