drm/radeon/radeon_drv: Move 'radeon_mmap()'s prototype to shared header

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/radeon/radeon_ttm.c:931:5: warning: no previous prototype for ‘radeon_mmap’ [-Wmissing-prototypes]
 931 | int radeon_mmap(struct file *filp, struct vm_area_struct *vma)
 | ^~~~~~~~~~~
