clk: export __clk_get_flags for modular clock providers

The common clock api provides some helpers for clk-providers but does not export these helpers. This hinders clk-providers to be built as modules. This patch adds __clk_get_flags() to the list of exported symbols.

I think this got merged slightly wrong. The EXPORT_SYMBOL_GPL macro came under clk_unprepare_unused_subtree() instead of under __clk_get_flags():

Of course this is not that important, but it's a bit confusing when you look at the code.
