[PATCHv2] clk: ti: omap3+: dpll: use non-locking version of clk_get_rate

[Tony Lindgren]

* Tero Kristo <t-kristo at ti.com> [160220 03:12]:
> 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.
