[PATCH 6/7] accel/qaic: Create a function to initialize BO

[Jeffrey Hugo]

From: Pranjal Ramajor Asha Kanojiya <quic_pkanojiy at quicinc.com>

This makes sure that we have a single place to initialize and
re-initialize BO.

Use this new API to cleanup release_dbc()

We will need this for next patch to detach slicing to a BO.
