[ Upstream commit 811dbc546f47559dc9d2098c612acfd47e32479e ]

The resolution property is not supposed to be set during reconfig.
Existing iris_drc_pending(inst) check is insufficient, as it doesn't
cover the first port setting change.

Extend the conditional check to also skip resolution setting when
the instance is in IRIS_INST_SUB_FIRST_IPSC.

Fixes: caf205548769 ("media: iris: Avoid updating frame size to firmware during reconfig")
