[ Upstream commit 6e5329c6e6032cd997400b43b8299f607a61883e ]

Do not emit a warning for extended firmware header fields that are
not used by kernel. This creates unnecessary noise to kernel logs like:

sof-audio-pci 0000:00:1f.3: warning: unknown ext header type 3 size 0x1c
sof-audio-pci 0000:00:1f.3: warning: unknown ext header type 4 size 0x10
