Make drm support modular to reduce kernel size (-620 KiB):

       text    data     bss     dec     hex   filename
    12211122 1392076  338520 13941718  d4bbd6 vmlinux.before

Slightly controversial:
  - Does anyone need drm for boot testing?

Only the tegra driver is affected, so let's ask the tegra
maintainers.

And the qcom maintainers.

CONFIG_DRM_MSM also changes from m to y, but this is not visible in
multi_v7_defconfig due to CONFIG_DRM_MSM_FBDEV=y and defconfig reduction...

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
