pxa_cpufreq_init_voltages() is marked __init but usually inlined into
the non-__init pxa_cpufreq_init() function. When building with clang,
it can stay as a standalone function in a discarded section, and produce
this warning:

WARNING: vmlinux.o(.text+0x616a00): Section mismatch in reference from the function pxa_cpufreq_init() to the function .init.text:pxa_cpufreq_init_voltages()
The function pxa_cpufreq_init() references
the function __init pxa_cpufreq_init_voltages().
This is often because pxa_cpufreq_init lacks a __init
annotation or the annotation of pxa_cpufreq_init_voltages is wrong.

Fixes: 50e77fcd790e ("ARM: pxa: remove __init from cpufreq_driver->init()")
