Subject: [PATCH] Rework drm modules selection on ARM
This is a wip version as plymouth still doesn't work for me
1/ On arm, aliases use a different path (soc)
2/ host1x has the matching device aliases
whereas tegra_drm has the crt_init symbol
3/ Others ARM drivers may behave similarly
4/ backlight and pwm_bl also need to be bundled.
I'm currenly testing with fedora kernel 3.14 or 3.15
