auxdisplay: ht16k33: select framebuffer helper modules 

The new driver caused a rare randconfig failure:

drivers/auxdisplay/ht16k33.o:(.data.ht16k33_fb_ops+0xc): undefined reference to `fb_sys_read'
drivers/auxdisplay/ht16k33.o:(.data.ht16k33_fb_ops+0x10): undefined reference to `fb_sys_write'

This selects the respective helper modules.
