[v3,2/4] drm/vkms: Switch to managed for encoder

Commit Message

Louis Chauvet Sept. 12, 2024, 1:25 p.m. UTC

The current VKMS driver uses non-managed function to create encoders. It
is not an issue yet, but in order to support multiple devices easily,
convert this code to use drm and device managed helpers.
