Subject: [PATCH] PM: clk: remove unused of_pm_clk_add_clk

From: "Dr. David Alan Gilbert" <linux@...blig.org>

The last use of of_pm_clk_add_clk() was removed by 2019's
commit fe00f8900ca7 ("irqchip/gic-pm: Update driver to use clk_bulk APIs")

Remove it.

Note that the plural version of_pm_clk_add_clks() is still being
used and is left.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
