Title:
  Add installer support for iwlmvm adapters

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Xenial:
  Fix Released
Status in linux source package in Bionic:
  Fix Released
Status in linux source package in Disco:
  Fix Released
Status in linux source package in Eoan:
  Fix Released

Bug description:
  [Impact]
  Some wireless Intel cards that use the iwlmvm driver are not available during installation.

  [Test Case]
  Boot up the Ubuntu installer on a system with an iwlmvm adapter, and try using the wireless connection.

  [Fix]
  Add the missing sub-module to debian.master/d-i/nic-modules

  [Regression Potential]
  As we're including a new sub-module, this change makes the installer susceptible to bugs present in the iwlmvm driver. Other than that, this change should not introduce any new regressions as it doesn't change any driver code.
