ACPI: fix a section mismatch

WARNING: drivers/acpi/acpi.o(.text+0xeda): Section mismatch in reference from the function acpi_os_initialize1() to the function .init.text:set_osi_linux() The function acpi_os_initialize1() references
the function __init set_osi_linux().
This is often because acpi_os_initialize1 lacks a __init
annotation or the annotation of set_osi_linux is wrong.

Fix this section mismatch.
