[PATCH v2] clk: Provide dummy of_clk_get_from_provider() for compile-testing

[Geert Uytterhoeven <geert+renesas@glider.be>]

When CONFIG_ON=n, dummies are provided for of_clk_get() and
of_clk_get_by_name(), but not for of_clk_get_from_provider().

Provide a dummy for the latter, to improve the ability to do
compile-testing.  This requires removing the existing dummy in the
Lantiq clock code.

Fixes: 766e6a4ec602d0c1 ("clk: add DT clock binding support")
