POWERPC: Bring the fs_no calculation to the relevant SoC enumeration
The fs_no mean used to be fs_enet driver driven, hence it was an enumeration across all the possible fs_enet "users" in the SoC. Now, with QE on the pipeline, and to make DTS descriptions more clear, fs_no features relevant SoC part number, with additional field to describe the SoC type. Another reason for that is now not only fs_enet is going to utilize those stuff. There might be UART, HLDC, and even USB, so to prevent confusion and be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were updated in that concern, as well as the relevant DTS.
