kernel: armsr: move framebuffer and DRM related options to top-level

The armv8 configuration has more features enabled compared to armv7,
as armv8 is intended to run on a selection of real hardware, while
armsr/armv7 almost always runs only in QEMU.

Some kmod dependency issues were appearing on armv7 builds which
did not appear elsewhere. To minimise these issues, we will
move the framebuffer feature set to the top level of the target.
