drm/msm/sde: add secure use case properties
This change adds custom PLANE(fb_translation_mode) and
CRTC(security_level) properties for supporting secure use case.
Plane property identifies the translation requirement for the
planes. CRTC property speicifies what planes could be attached
to this CRTC.
