clk: samsung: Use clk_hw API for calling clk framework from clk notifiers
[ Upstream commit 1da220e3a5d22fccda0bc8542997abc1d1741268 ]
clk_notifier_register() documentation states, that the provided notifier
callbacks associated with the notifier must not re-enter into the clk
framework by calling any top-level clk APIs. Fix this by replacing
clk_get_rate() calls with clk_hw_get_rate(), which is safe in this
context.
