Subject: [PATCH v3 2/5] Documentation: ioctl-number: Carve out some identifiers for use by sample drivers

32 IDs should be plenty (at yet, not too greedy) since a lot of sample
drivers will use their own subsystem allocations.

Sample drivers predominately reside in <KERNEL_ROOT>/samples, but there
should be no issue with in-place example drivers using them.
