This reverts part of commit 4859cdf97fd9a260036e148e25f0b78eb393df1e.
Modification of meta/classes/create-spdx-2.2.bbclass is not backported,
so no need to consider it.
In the commit, it updates spdx according to bitbake change. But the
bitbake commit
* 2515fbd10 fetch: Drop multiple branch/revision support for single git urls
doesn't backport for scarthgap.
So revert the other parts of the commit 4859cdf97fd9a260036e148e25f0b.
