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).
