x86: Activate CONFIG_FB_DEVICE

This adds the legacy /dev/fb* device file for kernel 6.6 again.
Linux upstream commit 701d2054fa31 ("fbdev: Make support for
userspace interfaces configurable") made this configurable and we
deactivated this option by default for kernel 6.6. On x86 we are not
space constrained and some users need this legacy interface.

Fixes: #15222
