[v1,7/8] thermal: intel: intel_pch: Rename board ID symbols

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Use capitals in the names of the board ID symbols and add the PCH_
prefix to each of them for consistency.

Also rename the board_ids enum accordingly.

No intentional functional impact.

Now struct board_info has "name" field only, so maybe we can remove
struct board_info, and use a "static const char *" array instead?

BTW, I'm building a kernel with this patch series as well as 
https://patchwork.kernel.org/project/linux-pm/list/?series=717084,
will update the test result later.

thanks,

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.
