[PATCH 38/85] drivers: gpu: Move prototype declaration to header file radeon.h from radeon_acpi.c

[Rashika Kheria]

Move prototype declarations of functions radeon_pm_acpi_event_handler()
to header file drm/radeon/radeon.h because it is used by more than one
file.

This eliminates the following warning in drm/radeon/radeon_pm.c:
drivers/gpu/drm/radeon/radeon_pm.c:68:6: warning: no previous prototype for ‘radeon_pm_acpi_event_handler’ [-Wmissing-prototypes]
