drm: xilinx: fb: Define some functions as static

Fix some sparse warnings:
drivers/gpu/drm/xilinx/xilinx_drm_fb.c:141:5: warning: symbol 'xilinx_drm_fb_helper_pan_display' was not declared. Should it be static?
drivers/gpu/drm/xilinx/xilinx_drm_fb.c:197:1: warning: symbol 'xilinx_drm_fb_ioctl' was not declared. Should it be static?
