Request add hibmc_drm into buster aarch64 netboot image

[She Kairui <shekairui@gmail.com>]

Hello，

I'm trying to install Debian buster on to the Huawei Kunpeng arm64 server, found that the installation graphic output not show up via the server BMC virtual console. 

Because Huawei  Kunpeng arm64 server BMC chip is hibmc, the OS need hibmc_drm.ko to work with it, currently this kernel module is not included in the netboot initrd (http://ftp.debian.org/debian/dists/stable/main/installer-arm64/20190702+deb10u1/images/netboot/netboot.tar.gz) .

I have verified the BMC virtual console graphic output works well by adding hibmc_drm.ko into the netboot initrd.  Could you please help evaluating add the hibmc_drm udeb into the netboot initrd by default?

Thanks
