ACPI: scan: fix undeclared variable warnings by including sleep.h
There are two pieces of data being exported from drivers/acpi/scan.c (acpi_device_lock and acpi_wakeup_device_list) that don't have their definitions declared in anything scan.c is including. Fix the following sparse warnings by including sleep.h to add the declarations of acpi_device_lock and acpi_wakeup_device_list to fix the followng sparse warnings: drivers/acpi/scan.c:42:1: warning: symbol 'acpi_device_lock' was not declared. Should it be static? drivers/acpi/scan.c:43:1: warning: symbol 'acpi_wakeup_device_list' was not declared. Should it be static?
