drm: Handle connector tile support only for modes that match tile size

Browse source

DRM Fb driver expects multiple CRTCs if it sees connector->has_tile
is set, but we need to handle tile support and look for multiple CRTCs
only for the modes that match the tile size. The other modes should
be able to be displayed without tile support or uisng single CRTC.

This patch adds the check to match the tile size with requested mode
to handle the tile support.
