Link capability categorized as Single Link Operation (SLO) and Multi Link
Operation (MLO).
* Intra-chip SLO/MLO refers to links present within a chip
* Inter-chip SLO/MLO refers to links present across multiple chips
Currently, driver uses a boolean variable to represent intra-chip SLO/MLO
capability. To accommodate inter-chip SLO/MLO capabilities within the same
variable, modify the existing variable name and type. Define a new
enumeration for the link capabilities to accommodate both intra-chip and
inter-chip scenarios. Populate the enum based on the supported
capabilities.
