TT#38454 Move firmwares from deployment.sh to NGCP metapackage ngcp-hardware-support

In the past those packages were installed on CE/PRO/Carrier by
deployment.sh on debootstrap process. Migrate them to metapackages
to ensure they are always available on NGCP.

P.S. Why do we need to install those firmwares:
> # required e.g. for "Broadcom NetXtreme II BCM5709S Gigabit Ethernet"
> # lacking the firmware will result in non-working network on
> # too many physical server systems, so just install it by default
