msm: apr: Use correct LPASS name for SSR notification registration

Update APR SSR notification registration call to use correct LPASS
subsystem name for 8960 and 8974.

LPASS Subsystem uses "lpass" string for 8960 and "adsp" string for
8974 chipsets for SSR framework registration.

Fix adsp state checking in APR LPASS callback for after powerup
case.
