drm/sysfb: Convert to atomic_create_state

Browse source

drm_sysfb_plane_reset() handles both state creation and teardown of
the previous state through the reset hook, which conflates initial
state allocation with hardware and software reset at resume.

Convert it to drm_sysfb_plane_atomic_create_state(), which only
allocates and initializes a pristine state using
__drm_gem_shadow_plane_state_init(). Update DRM_SYSFB_PLANE_FUNCS to
use .atomic_create_state instead of .reset.
