[ARM] omap: create a proper tree of clocks
Traditionally, we've tracked the parent/child relationships between clk structures by setting the child's parent member to point at the upstream clock. As a result, when decending the tree, we have had to scan all clocks to find the children. Avoid this wasteful scanning by keeping a list of the clock's children.
