For the other compatibles, the enum entries and const/fallback
entries are different. For the 9574 & 8074 case, we want to have
qcom,ipq8074-tsens as both enum and const/fallback entry. Hence,
if we don't have the first hunk, dtbs_check fails for 8074
related dtbs

	ipq8074-hk01.dtb: thermal-sensor@4a9000: compatible: 'oneOf' condition
		['qcom,ipq8074-tsens'] is too short

	ipq8074-hk10-c2.dtb: thermal-sensor@4a9000: compatible: 'oneOf' condition
		['qcom,ipq8074-tsens'] is too short

	ipq8074-hk10-c1.dtb: thermal-sensor@4a9000: compatible: 'oneOf' condition
		['qcom,ipq8074-tsens'] is too short

I'm not sure of the correct solution. Having the first hunk
solves the above dtbs_check errors, so went with it. I'm able to
avoid dtbs_check errors with just one entry in the first hunk.

 	+      - const: qcom,ipq8074-tsens

Please let me know if there is a better way to resolve this or we
can have just the 8074 entry in the first hunk.

Thanks
