[PATCH RESEND] clk: export __clk_get_flags for modular clock providers

[Sebastian Hesselbarth]

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.
