Good point.

I think that the last patch in the series can be replaced with the
appended one.

Subject: [PATCH] thermal: intel: intel_pch: Drop struct board_info

Because the only member of struct board_info is the name, the
board_info[] array of struct board_info elements can be replaced with
an array of strings.

Modify the code accordingly and drop struct board_info.

No intentional functional impact.
