msm: smem_log: Initialize SMEM log after SMD

The smem_log dependency on SMSM is a legacy dependency that waited
for the modem to allocate the SMEM items before smem_log was initialized.
Now that smem_log can allocate the items first if necessary, it no longer
needs to wait for the modem since the only true dependency is that the
SMD module has initialized SMEM.

Update dependency information to initialize smem_log once SMD has
been initialized.
