[PATCH v1 2/5] platform/x86: fujitsu: Reorder code to avoid forward declarations

[Rafael J. Wysocki]

From: "Rafael J. Wysocki" <rafael.j.wysocki@xxxxxxxxx>

Move the definitions of acpi_fujitsu_bl_notify() and
acpi_fujitsu_laptop_notify() along with some helpers above
the definitions of the functions that will refer to them
after subsequent changes, to avoid having to add forward
declarations of them.

No intentional functional impact.
