As the code in this file is being executed within irq context in some
cases, we must avoid the clk_get_rate which uses mutex internally.
Switch the code to use clk_hw_get_rate instead which is non-locking.
This fixes an issue where PM runtime will hang the system if enabled
with a serial console before a suspend-resume cycle.
