ti-linux-fw: Split firmware in to machine packages

Browse Source 
Firmware, like kernel modules, may be only relevant to a small subset of
hardware. Shipping all firmware for all hardware can waste space. For
this reason modules are split out into packages, and the same should
be done for firmware.

What we do currently is change the content of the package itself based
on what device we are building for. Having a package change content for
each machine means we cannot generate one image that supports multiple
machines, nor host a common machine agnostic package repo.

Instead we can generate different packages for the different firmwares
and only include the firmware packages needed for each machine.
