Not needed more.

framebuffer not working with dtoverlay=vc4-fkms-v3d on RPi3 aarch64.

The Raspberry Pi 4 has hardware acceleration, there is no need to
use special programs.
bluetooth is needed only on a desktop.

While this argument can only have one "EFI" value.
Thus, the problem of building an image for Raspberry Pi on armh,
where there is no grub-efi, was solved.

This needed for live.

The 'splash' boot argument must be cleared so that it is not enabled
for rootfs and livecd that do not have plymouth installed.

Forgot to disable up after finishing debugging.

It is very strange that earlier in STAGE1 added kernel modules from
a variable STAGE1_KMODULES_REGEXP only.
This commit makes the drm feature work properly.

use/bootloader/uboot needed uboot packages.

Removed from Sisyphus.

ncpfs has been removed from Sisyphus.

use/repo/main for vm targets will now create and enable the main
repository in /ALTLinux on rootfs.

The drm feature solves the problem of creating a common entry
point for adding kernel drm modules for different package lists.
The need for allocation into a separate feature arose from one
parties to the need to make a switch between free and proprietary
NVIDIA driver, on the other, because of the need to add only drm
modules kernels for purposes such as use/stage2/kms and use/plymouth.

Also no more switch needed for RADEON, as only the free video driver
remains.
