clk: samsung: exynos-audss: Replace syscore PM with platform device PM

Browse Source 
Exynos AUDSS clock driver has been already converted to platform driver,
so remove the dependency on the syscore ops - the last remaining
non-platform driver feature. Platform device's system sleep PM provides
all needed infrastructure for replacing syscore-based PM, so do it now.
