MIPS: BMIPS: Fix section mismatch warning

Remove the __init annotation from bmips_cpu_setup() to avoid the
following warning.

WARNING: vmlinux.o(.text+0x35c950): Section mismatch in reference from the function brcmstb_pm_s3() to the function .init.text:bmips_cpu_setup()
The function brcmstb_pm_s3() references
the function __init bmips_cpu_setup().
This is often because brcmstb_pm_s3 lacks a __init
annotation or the annotation of bmips_cpu_setup is wrong.
