hdata/vpd: Rework vpd node creation logic

Presently we traverse SLCA structure to create various FRU nodes under /vpd
node. We assumed that children are always contiguous. It happened to be
contiguous in P8 and worked fine, but failed in P9 system. So it ended up
populating duplicate node under wrong parent. Also failed to populate some
of the nodes.

Unfortunately there is no way to reach all the children of a given parent
from parent node :-( Hence we have to rework vpd creation logic.

This patch goes through all the SLCA entries serially and creates vpd node.
Assumptions:
  - SLCA index is always serial (0..n)
  - When we traverse serially parent entry comes before child
  - Redundant resources are always consecutive
  - Populate node if SLCA has 'installed' and 'VPD collected' bit set
