PM / clk: export symbols for existing pm_clk_<...> API fcns
While trying to convert a DMA driver from bool to tristate, we encountered the following: ERROR: "pm_clk_add_clk" [drivers/dma/tegra210-adma.ko] undefined! ERROR: "pm_clk_create" [drivers/dma/tegra210-adma.ko] undefined! ERROR: "pm_clk_destroy" [drivers/dma/tegra210-adma.ko] undefined! ERROR: "pm_clk_suspend" [drivers/dma/tegra210-adma.ko] undefined! ERROR: "pm_clk_resume" [drivers/dma/tegra210-adma.ko] undefined! Since in principle there is nothing preventing these functions from being used in modular code as well as builtin, we add the export of them. We expand the scope to also include: pm_clk_add of_pm_clk_add_clks pm_clk_remove pm_clk_remove_clk pm_clk_init pm_clk_runtime_suspend pm_clk_runtime_resume pm_clk_add_notifier ...since these functions are also non-static and presumably form part of the existing API used by other drivers that may become modular in the future.
