[PATCH v2] libdrm: add exynos drm support

Ok, I've pushed this with a couple minor cleanups:
1) remove .pc file (which is generated from .pc.in file)
2) below patch to fix a compile error (maybe not seen w/ older gcc?)
3) remove DRM_IOCTL_EXYNOS_GEM_USERPTR because I think that part is
still being debated on kernel side.. it can be added back in another
patch once there is a conclusion on the kernel side
