Subject: [PATCH 5.4 268/408] clk: keystone: sci-clk: fix parsing assigned-clock data during probe

From: Tero Kristo <t-kristo@...com>

[ Upstream commit 2f05cced7307489faab873367fb20cd212e1d890 ]

The DT clock probe loop incorrectly terminates after processing "clocks"
only, fix this by re-starting the loop when all entries for current
DT property have been parsed.

Fixes: 8e48b33f9def ("clk: keystone: sci-clk: probe clocks from DT instead of firmware")
