pcie_bifurcation: Fetch bifurcation at a PCIe slot with hardcoded values
This will read a json config and return the bifurcation based on that. It will read the configure file in a persistent file to see if it is valid machine config and return the bifurcation information accordingly.
For example, If it is valid config, it will return 8x8 for PE1,3,4,6.
Tested: Unit tests passed.
Physical Tests.
PE0 -> no bifurcation PE1 -> x8x8
