Nitin Kumbhar a3d5511dea platform: nvadsp: use smem for adsp freq update

Instead of using mailbox to communicate change in adsp cpu
freq, update it in adsp os args from ccplex-adsp shared
memory. This adsp freq update is needed by EDF scheduler
for scheduling EDF threads. The EDF scheduler gets
current adsp freq from shared memory instead of
scheduler callback.

However, for APE1 (i.e. chips = T21x), timer prescalar
must still be updated through mailbox each time adsp cpu
freq is changed.
