Remove the usage of refcount dsp_d0_sref, and use bool flag dsp_d0 to denote is the DSP target state is D0 or D0ix (Low power mode). This will simplify the logic of use of LPS and clock switching. Signed-off-by: Keyon Jie <yang.jie@linux.intel.com>

Note: Once the clock switching is decoupled from the dsp pm-runtime (d0 override), the low power scenarios (LPS) should be active by override bitmap to enable multiple clients, not just the host through pm_gate IPC. |
