[PATCH 0/4] Use num of pipes in joiner helpers

[Ankit Nautiyal <ankit.k.nautiyal@intel.com>]

Currently few joiner helpers pass joiner flag to represent if bigjoiner
is used. To scale this for ultrajoiner, enhance these helpers to use num
of pipes instead of joiner flag. This new approach is adaptable to various
joiner configurations with 1 (no joiner), 2 (big joiner) and forthcoming 4
(ultrajoiner) pipes.

This patch series is a spin off from original series for ultrajoiner
basic functionality [1]. Few of the preparatory patches are taken here for
review and merge before the other core patches of the series.
