msm: Makefile: Move SMD initialization earlier

The subsystem restart drivers need access to smsm APIs and those
APIs rely on the SMD driver being initialized. The subsystem
restart drivers are lower down in the Makefile so they probe
after the SMD driver probes. Once we merge the subsystem restart
drivers into the PIL drivers smsm APIs will be called before the
SMD driver probes causing probe failures.

Move the compilation of SMD earlier so that SMD will probe before
the PIL drivers and calls to smsm APIs will still work.
