Stanislaw Gruszka 3ff6edbc17 accel/ivpu: Do not use SSID 1 
The SSID=1 is used by the firmware as default value in
case SSID mapping is not initialized. This allows
detecting use of miss-configured memory contexts.
The future FW versions may not allow using SSID=1.

SSID=65 is valid value, number of contexts are limited
by number of available command queues, but SSID can be
any u16 value.
