Subject: [PATCH] acpi: Fix section mismatch warning in osl.c

Function acpi_os_initialize1() calls acpi_osi_setup_late() which is in
.init.text section and gets called from acpi_bus_init which is in
.init.text section. So mark acpi_os_initialize1() with __init. And
declaration of __init acpi_osi_setup_late has been removed, cause its
defination is above called function.

 WARNING: drivers/acpi/acpi.o(.text+0x460): Section mismatch in
reference from the function acpi_os_initialize1() to the function
.init.text:acpi_osi_setup_late()
The function acpi_os_initialize1() references
the function __init acpi_osi_setup_late().
This is often because acpi_os_initialize1 lacks a __init
annotation or the annotation of acpi_osi_setup_late is wrong.

Thanks,
Rakib
