The factory-reset-toggle GPIO can have its state changed by physically
toggling SWITCH_RESET_N. If this GPIO is in a different state than it
was during the last boot, it triggers a BMC factory reset.
Tested: Added extra files to /var. Verified that a reset from a
physical toggle caused these files to be removed. Verified that resets
from the REST API and from setting rwreset to true still function
properly. Verified that repeated rebooting without calling for a reset
does not inadvertently trigger a reset.

To enable factory resets, the mmc-init.sh script checks on reboot if
the environment variable rwreset is set to "true". If it is, the rw
parts of the file system that users may have modified are reformatted
to remove all user changes and rwreset is set to "false".
Tested: Add a file to /var and use fw_setenv to set rwreset to true.
Reboot the machine and verify that the added file is gone and rwreset
is set to false.

Add fsck.ext4 to the eMMC initramfs to be able to manually correct
ext4 errors, fsck.ext4 already exists in user space.
Tested: Verified it was added to the initramfs:
/ # which fsck.ext4
/sbin/fsck.ext4
/ # fsck.ext4 /dev/mmcblk0p2

This init script mounts the rootfs based on the root u-boot env
variable, mounts the read-write filesystem and sets up the overlay.
