Bug#1010346: linux-image-cloud-amd64: Enable CONFIG_FB_EFI=y in Buster Cloud Kernel

[Vasudev Kamath <vasudev@debian.org>]

Package: linux-image-cloud-amd64
Version: 4.19+105+deb10u15
Severity: important

Dear Maintainer,

Booting a KVM based VM with UEFI enabled using Buster image with cloud kernel will have
a non working VNC console. Console seems to be frozen on debugging we figured out that 
its because buster cloud kernel does not have CONFIG_FB_EFI enabled.

This issue is not present in Bullseye kernel as it was enabled in following commit [1].
Can we also enable same option for Buster cloud kernel?. Else for using VNC like console
VM image needs to be running regular kernel (linux-image-amd64).

Thanks and Regads,
Vasudev
