Input: applespi - select CRC16 module
In some rare randconfig builds, CRC16 is disabled, which leads to a link error: drivers/input/keyboard/applespi.o: In function `applespi_send_cmd_msg': applespi.c:(.text+0x449f): undefined reference to `crc16' drivers/input/keyboard/applespi.o: In function `applespi_verify_crc': applespi.c:(.text+0x7538): undefined reference to `crc16' This symbol is meant to be selected for each user in Kconfig, so do that here as well.
