[PATCH v3 05/26] media: iris: Allow substate transition to load resources during output streaming

[Dikshita Agarwal <quic_dikshita@quicinc.com>]

A client (e.g., GST for encoder) can initiate streaming on the capture
port before the output port, causing the instance state to transition to
OUTPUT_STREAMING. When streaming is subsequently started on the output
port, the instance state advances to STREAMING, and the substate should
transition to LOAD_RESOURCES.

Previously, the code blocked the substate transition to LOAD_RESOURCES
if the instance state was OUTPUT_STREAMING. This update modifies the
logic to permit the substate transition to LOAD_RESOURCES when the
instance state is OUTPUT_STREAMING, thereby supporting this client
streaming sequence.
