[PATCH] clk: meson: meson8b: Simplify notifier clock lookup

[Chen-Yu Tsai]

The driver registers a clock notifier by first getting the name of one
of its clocks it just registered, then uses the name to look up the
clock. The lookup is not needed, since each clock provider already
has a clock attached to it. Use that instead to get rid of a
__clk_lookup() call.

Found this could be simplified while looking through some clk core code.
