The code wrapped in '#ifdef PREBOOT_SUPPORT' was added for
queue context initialization specifically for A0 silicon.
As A0 silicon has gone for a long time, the code should be
removed at all. In addition, the checks of 'QV_RELEASE'
and 'PREBOOT_SUPPORT' are also not needed anymore and can
be removed.
