firmware-imx: Downgrade to v8.26.1

LF6.6.52_2.2.1 uses firmware-imx v8.26.1.
Version 8.27 ships an older wave6-vpu firmware, leading to kernel errors:
  wave6-vpu 4c480000.vpu: compatible firmware version is v3.0.0 or higher, but only v2.1.0

Downgrade to v8.26.1 to match the release and avoid this issue.

Fixes: b1601f3af7 ("firmware-imx: Upgrade to v8.27")
