drm/radeon/kms: change Kconfig text to reflect the new option.

Ingo pointed out that we really don't give the user enough warning to make
a decision here. So revise the Kconfig text with a better warning.

-          Choose this option if you want kernel modesetting enabled by default,
-          and you have a new enough userspace to support this. Running old
-          userspaces with this enabled will cause pain.

+          This is a completely new driver. It's only part of the existing drm
+          for compatibility reasons. It requires an entirely different graphics
+          stack above it and works very differently from the old drm stack.
+          i.e. don't enable this unless you know what you are doing it may
+          cause issues or bugs compared to the previous userspace driver stack.
 
           When kernel modesetting is enabled the IOCTL of radeon/drm
           driver are considered as invalid and an error message is printed
