DLPX-94068 With EFI boot, CONFIG_DRM is needed for proper VM console output on ESX

[tonynguien]

Problem

With EFI boot, removing CONFIG_DRM would take away the necessary framebuffer related modules that are needed for proper console output on ESX.

Solution

Eliminating CONFIG_DRM from our `resources/delphix_kernel_annotations` restores the necessary modules and ESX VM console output.

Testing Done

** BIOS

• Appliance build: https://selfservice-jenkins.eng-tools-prd.aws.delphixcloud.com/job/appliance-build-orchestrator-pre-push/11013/console
• Uploaded ova to performance ESX host and confirmed that the resulting ova comes up successfully and has console output. Did the same for AWS appliance VM
