On SM8250 (IRIS2) with firmware older than 1.0.087, the firmware could not handle a dummy device address for EOS buffers, so a NULL device address is sent instead. The existing check used IS_V6() alongside a firmware version gate:
if (IS_V6(core) && is_fw_rev_or_older(core, 1, 0, 87)) fdata.device_addr = 0; else fdata.device_addr = 0xdeadb000;
However, SC7280 which is also V6, uses a firmware string of the form "1.0.<commit-hash>", which the version parser translates to 1.0.0. This unintentionally satisfies the `is_fw_rev_or_older(..., 1, 0, 87)` condition on SC7280. Combined with IS_V6() matching there as well, the quirk is incorrectly applied to SC7280, causing VP9 decode failures.
Constrain the check to IRIS2 (SM8250) only, which is the only platform that needed this quirk, by replacing IS_V6() with IS_IRIS2(). This restores correct behavior on SC7280 (no forced NULL EOS buffer address).
