[Bug 1298070] [NEW] Flash-kernel shouldn't raise any errors while running inside vm instance

[Oleg Strikov]

Public bug reported:

While running flash-kernel inside vm instance on armhf I get the
following error:

$ flash-kernel
Unsupported platform.
$ echo $?
1

This happens because dtb is not provided (we don't need it) and /proc/cpuinfo contains the following information:
Hardware	: Dummy Virtual Machine
But we don't have description for this 'Dummy Virtual Machine' inside all.db.

This leads to a crash of curtin (ubuntu fast path installer) because it
checks the return code.

** Affects: flash-kernel (Ubuntu)
     Importance: Undecided
         Status: New

** Description changed:

- While running flash-kernel inside vm instance I get the following error:
