kernel: Use new FSI chardev system

The kernel has changed how the character devices are allocated by the
fsi driver. All of the in-tree users of fsi have been updated to use
this new system.

The changes include an optional feature improve the layout of userspace
API. This is controlled by the CONFIG_FSI_NEW_DEV_NODE option, which we
do not set yet.
