LoongArch: Move __arch_cpu_idle() to .cpuidle.text section
commit 3e245b7b74c3a2ead5fa4bad27cc275284c75189 upstream.
Now arch_cpu_idle() is annotated with __cpuidle which means it is in
the .cpuidle.text section, but __arch_cpu_idle() isn't. Thus, fix the
missing .cpuidle.text section assignment for __arch_cpu_idle() in order
to correct backtracing with nmi_backtrace().
The principle is similar to the commit 97c8580e85cf81c ("MIPS: Annotate
cpu_wait implementations with __cpuidle")
