[PATCH 11/11] drivers: acpi: Include header file in debugfs.c andrectify prototype declaration in internal.h

[Rashika Kheria]

Include header file internal.h in debugfs.c and change the return
value's type in header file internal.h.

This eliminates the following warning in debugfs.c:
drivers/acpi/debugfs.c:16:13: warning: no previous prototype for âacpi_debugfs_initâ [-Wmissing-prototypes]
