gpu: drm: panel-edp: Fix edp_panel_entry documentation

The edp_panel_entry members 'delay' and 'name' are documented, but
without the correct syntax for kernel doc.

This generates the following warnings:

drivers/gpu/drm/panel/panel-edp.c:204: warning: Function parameter or member 'delay' not described in 'edp_panel_entry'
drivers/gpu/drm/panel/panel-edp.c:204: warning: Function parameter or member 'name' not described in 'edp_panel_entry'

Fix them accordingly.
