Currently, DRM_PANEL_ILITEK_ILI9882T selects DRM_DISPLAY_DSC_HELPER
without ensuring DRM_DISPLAY_HELPER is also enabled, causing an unmet
dependency and build failure.

Other similar options select DRM_DISPLAY_HELPER, let's do the same here.

This unmet dependency bug was found by kconfirm, a static analysis tool
for Kconfig.
