mmcsd is the old non-CAM sdcard driver.  If you're using the MMCCAM
kernel it uses the new CAM-based sdcard driver and the old one is
removed from the kernel.

It's a bit non-intuitive, but saying "options MMCAM" in the config is
equivelent to also saying "device mmccam", and in sys/conf/files you'll
see that there are a variety of cam-based mmc and sdcard driver pieces
that are conditionally compiled based on 'mmccam'.
