HSI: Fix PM usage counter unbalance in ssi_hw_init

Browse source 
[ Upstream commit aa57e77b3d28f0df07149d88c47bc0f3aa77330b ]

pm_runtime_get_sync will increment pm usage counter
even it failed. Forgetting to putting operation will
result in reference leak here. We fix it by replacing
it with pm_runtime_resume_and_get to keep usage counter
balanced.
