rG28fefc441e3b: ufshci: add a control device node

Summary

The driver only exposed a CAM SIM. Userland had no way to reach the
device for anything that is not a SCSI command, so reading a descriptor
or an attribute was impossible.

Add /dev/ufshci%d as a root only node and the ioctl ABI header for it.
The node answers no ioctl yet. The header pulls in ufshci.h, which
declares bool only under _KERNEL, so include stdbool.h for userland the
way nvme.h already does.
