accel/ivpu: Initialize context with SSID = 1
Context with SSID = 1 is reserved and accesses on that context happen
only when context is uninitialized on the VPU side. Such access triggers
MMU fault (0xa) "Invalid CD Fetch", which doesn't contain any useful
information besides context ID.
This commit will change that state, now (0x10) "Translation fault" will
be triggered and accessed address will shown in the log.
