[PATCH 19/26] intel_pstate: constify local structures

[Julia Lawall]

For structure types defined in the same file or local header files, find
top-level static structure declarations that have the following
properties:
1. Never reassigned.
2. Address never taken
3. Not passed to a top-level macro call
4. No pointer or array-typed field passed to a function or stored in a
variable.
Declare structures having all of these properties as const.

Done using Coccinelle.
Based on a suggestion by Joe Perches <j...@perches.com>.

Signed-off-by: Julia Lawall <julia.law...@lip6.fr>

The semantic patch seems too long for a commit log, but is in the cover
letter.
