topology/cmake: add missing .m4 dependency, fixes incremental build

[marc-hb]

There was no [MAIN_]DEPENDS on the .m4 source file, so changes were not
triggering any rebuild.

The checkpatch WARNING: Misplaced SPDX-License-Identifier tag is a bug in checkpatch, it's triggered every time a code change is too close to the top of the file.

https://travis-ci.org/github/thesofproject/sof/builds/764043617 is the usual docker rate limit

https://sof-ci.01.org/sofpr/PR3945/build8445/devicetest/?model=CML_HEL_RT5682&testcase=check-suspend-resume-5 is the usual TIMEOUT

Try CI again, this should not break tests.

SOFCI TEST

[marc-hb]

https://sof-ci.01.org/sof-pr-viewer/#/build/PR3945/build6195635 has only TestGenericProcessorCompMultiCorePlb48000Hz32b32b4ch failing like this:

07:31:36.167        SNR value is smaller than acceptable value (80.00) on channel 0: 0.16

07:31:36.167       Wave verification failed on channel 1
07:31:40.853        SNR value is smaller than acceptable value (80.00) on channel 0: 1.71

07:31:40.853       Wave verification failed on channel 2
07:31:45.508        SNR value is smaller than acceptable value (80.00) on channel 0: -0.98

07:31:45.508       Wave verification failed on channel 3
07:31:51.038        SNR value is smaller than acceptable value (80.00) on channel 0: 0.80

Every other test is green. Can't be related to this.

https://sof-ci.01.org/sofpr/PR3945/build8452/devicetest/ is amazingly all green

@zrombel can you comment on the internal CI, it looks unrelated.
@marc-hb I've disabled Travis now since its going away and GH actions are now doing the same thing.

[zrombel]

Error is unrelated. I will check this test stability with master top.

@zrombel thanks - let us know when we can merge.

[zrombel]

PR is good to merge.
