[PATCH] cpufreq: intel_pstate: remove incorrect __initconst annotation

[PATCH] cpufreq: intel_pstate: remove incorrect __initconst annotation

[Arnd Bergmann]

We get a build warning about the newly introduced code in
intel_pstate_init_cpu() that references an __initconst variable after
it has been freed:

WARNING: vmlinux.o(.text+0xf9eca2): Section mismatch in reference from the function intel_pstate_init_cpu() to the variable .init.rodata:intel_pstate_hwp_boost_ids
The function intel_pstate_init_cpu() references
the variable __initconst intel_pstate_hwp_boost_ids.
This is often because intel_pstate_init_cpu lacks a __initconst
annotation or the annotation of intel_pstate_hwp_boost_ids is wrong.

This removes the annotation to keep the variable around at
runtime.

I see Rafael already addressed this.
