UBUNTU: [Config] Enable CONFIG_DRM_BOCHS as module for all archs

BugLink: https://bugs.launchpad.net/bugs/1872863
A recent grub2 SRU, LP #1864533, has forced the kernel to boot via the efi
stub, instead of the grub linux loader. This causes problems for QEMU/KVM
virtual machines which use the VGA=std video device, as the efifb driver
yields an unreadable garbled screen. The correct framebuffer driver in
this situation is bochs-drm, and modprobing it fixes the issues.

CONFIG_DRM_BOCHS was disabled in LP #1378648 due to bochs-drm causing problems
in a PowerKVM machine. This problem appears to be fixed now, and bochs-drm
has been re-enabled for Disco and up, in LP #1795857 and has been proven safe.

Re-enable bochs-drm again as a module for all architectures to ensure that
QEMU/KVM virtual machines with VGA=std video settings have a functional
framebuffer.
