[ Upstream commit 52a518019ca187227b786f8b8ee20869a97f3af4 ]
In ufshcd_host_reset_and_restore(), ufshcd_set_clk_freq() is called to scale clock rate. However, this did not call vops->clk_scale_notify() to inform platform driver of clock change.
Call ufshcd_scale_clks() instead so that clock change can be properly handled.
