I've already pointed that this is a bad style solution. It will also not 
work in the following cases:

1. exynos drm and samsung-dsim compiled as modules - samsung-dsim 
module, once loaded, will register the driver and exynos_drm won't be 
able to register the exynos_dsi.

2. multi-arch case - if one compiles a kernel (disto-style) with drivers 
for both supported architectures (exynos and imx) - in such case it will 
not work on imx, because exynos_drm driver will always register 
exynos_dsi driver first (even if the kernel is booted on non-exynos board).

Best regards
