asu: revert sanitize

[map-b]

Since it seems there is no enough review time #1533 and the PR fixing the underlying issue which misleaded to the referenced revert commits has been merged:

• sunxi: image: sync target profiles names with DT compatible openwrt#21095

maybe just reverting to an known working state have better luck.

This would allow to use firmware-selector for the gl-mt2500 MaxLinear PHY case even Owut or Luci ASU app with the workaround of echo "glinet_gl-mt2500" > /tmp/sysinfo/board_name for the MaxLinear users.

The key here, IMHO, is that we have to make clearer the difference between "profile" and "DT compatible string" and for that I am thinking about some variable/messages renames could help also, but in order to prioritize, the code implied in the proposed reverts is the key and I think it goes in opposite direction.
#1525 (comment)
Right now we got this when generating the app.profiles[version][target]
