clk: qcom: common: fix legacy board-clock registration

Browse source 
[ Upstream commit 43a51019cc ]

Make sure to search only the child nodes of "/clocks", rather than the
whole device-tree depth-first starting at "/clocks" when determining
whether to register a fixed clock in the legacy board-clock registration
helper.
