Commit Message

Strictly encode patterns of supported hw_variants of firmware files
the kernel driver supports requesting. This now includes many missing
and previously undeclared module firmware files for 0x07, 0x08,
0x11-0x14, 0x17-0x1b hw_variants.

This especially affects environments that only install firmware files
declared and referenced by the kernel modules. In such environments,
only the declared firmware files are copied resulting in most Intel
Bluetooth devices not working. I.e. host-only dracut-install initrds,
or Ubuntu Core kernel snaps.

 Changes since v3:
 - Hopefully pacify trailing whitespace from GitLint in this optional
   portion of the commit.

 Changes since v2:
 - encode patterns for 0x17 0x18 0x19 0x1b hw_variants
 - rebase on top of latest rc tag

 Changes since v1:
 - encode strict patterns of supported firmware files for each of the
   supported hw_variant generations.
