Ringing IPA MHI event ring doorbell is done at MHI device
during MHI channel start. This is done after the rings
are allocated. The ring write pointer updated by the host is
used as the doorbell value. Doorbell ringing is required
in order to supply event credits to GSI H/W.

them during driver initialization.
This change adds validation steps to each firmware before
loading: load addresses, memory sizes, firmware sizes and
more...
