We make the following changes to the documentation of drm leases to make it easier to reason about their usage. In particular, we clarify the lifetime and locking rules of lease fields in drm_master: 1. Make it clear that &drm_device.mode_config.idr_mutex protects the lease idr and list structures for drm_master. The lessor field itself doesn't need to be protected as it doesn't change after it's set in drm_lease_create. 2. Add descriptions for the lifetime of lessors and leases. 3. Add an overview DOC: section in drm-uapi.rst that defines the terminology for drm leasing, and explains how leases work and why they're used.
