[PATCH 2/2] drivers: clk: clk.c: Make clk_is_orphan() dependent of CONFIG_OF

[Murilo Opsfelder Araujo <mopsfelder@gmail.com>]

The function clk_is_orphan() is called only by
__of_clk_get_from_provider(), which depends on CONFIG_OF, so it does
make sense the move.

This change also gets rid of the following build message when CONFIG_OF
is not set:

drivers/clk/clk.c:2231:13: warning: ‘clk_is_orphan’ defined but not used [-Wunused-function]
