[Accel-config] [PATCH v1] accel-config: While initing devices also init groups

From: Ramesh Thomas <ramesh.thomas(a)intel.com>

Grouped workqueues and engines rely on state stored in structures
associated with groups. Initialize the groups at the time of device init
so they are available when workqueues are enabled. Flags are used to
ensure groups do not get initialized again if they are already
initialized once.
