Subject: [PATCH] fbdev/sa1100fb: Remove even more dead code

This function lost its only call site as part of
earlier dead code removal, so remove it as well:

drivers/video/fbdev/sa1100fb.c:975:21: error: unused function 'sa1100fb_min_dma_period' [-Werror,-Wunused-function]

Fixes: 390e5de11284 ("fbdev/sa1100fb: Remove dead code")
