[PATCH v3 2/4] drm/vkms: rename cursor to plane on ops of planes composition

[Melissa Wen <melissa.srw@gmail.com>]

Generalize variables and function names used for planes composition
(from cursor to plane), since we will reuse the operations for both
cursor and overlay types.

No functional change.
