ENGR00132894 usb: clk_get should not be called at IRQ context
The old implementation will clk_get/clk_put for each clk on/off operation.
As some clk on/off operation would be IRQ context.
So, it will ocurr the error like "schedule at atomic context".
The new implementation will only call clk_get at usb initialization,
and clk_put at usb de-initialization.
The driver's clock on/off will only call clk_enable/clk_disable.
