drm/exynos: mic: convert to component framework
MIC is SoC component and important part of kms pipeline on Exynos5433, so convert it to use component framework like other KMS/CRTC drivers. MIC driver is already listed on KMS component driver list in Exynos DRM core, so without this conversion, initialization of Exynos DRM core fails on Exynos 5433 SoC.
