firmware: qcom: scm: initialize tzmem before marking SCM as available
commit 87be3e7a2d0030cda6314d2ec96b37991f636ccd upstream.
Now that qcom_scm_shm_bridge_enable() uses the struct device passed to
it as argument to make the QCOM_SCM_MP_SHM_BRIDGE_ENABLE SCM call, we
can move the TZMem initialization before the assignment of the __scm
pointer in the SCM driver (which marks SCM as ready to users) thus
fixing the potential race between consumer calls and the memory pool
initialization.
