platform: msm_shared: Remove TZ logging on default.

Add change to remove scm call to register shared
buffer to TZ. This is to avoid invalid pointer
access by TZ when TZ_LOG driver is not enabled in
HLOS because then the pointer in TZ will still hold
the buffer address send by LK which is invalid when
HLOS comes up.
