[PATCH v6 2/4] drm/exynos: mic: Fix parse_dt function

[Hoegeun Kwon <hoegeun.kwon@samsung.com>]

The OF graph is not necessary because the panel is a child of
dsi. therefore, the parse_dt function of dsi does not need to
check the remote_node connected to the panel. and the whole
parse_dt function should be refactored later.
