ecore-drm2: Add support for specifying a particular drm card
Summary: There are cases where the drm card that we wish to run on is not always the first card (ie: card1, card2, etc). In our previous code, we would always start searching at card0 and if found we would always use that card. This patch allows a card to be specified in the environment that can be searched for and used. For example, if we specify ECORE_DRM2_CARD=card1 than that card will be searched and used if found. This also allows wildcard searches such as ECORE_DRM2_CARD=card[1-9]* which can be used to skip the first card (card0).
