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

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")
Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>

v2:
  - Remove conflicting dummy in Lantiq clock code (reported by 0day).
