ASoC: SOF: ext_manifest: use explicit number for elem_type

[fredoh9]

Extend manifest replace extended FW boot data(in fw_ready section). This is obsolete from SOF firmware.

Fixes : #2491

I checked with SOF FW v1.6 and v1.5.1.
Without sdev->info_windows, there are many IPC errors. This prevent having sof soundcard. I will close this PR.

I dropped cleaning up extended data after fw_ready because it breaks backward compatibility. But setting explicit numbers for ext manifest enum is good to go.
