[PATCH] clk: export function clk_disable_unused()

[Jim Quinlan <jim2101024@gmail.com>]

For Broadcom STB chips, clocks may come up after resume in an "on"
state, so calling clk_disable_unused() again will turn off unused
clocks.  This commit exports clk_disable_unused() so it may be
called in such cases.
