[coreboot] libpayload and LGPL code

[Paul Menzel]

Dear coreboot folks,

Himanshu Chauhan pushed the change set `libpayload: Add Virtio layer and
storage device support` for review [1]. It’d be great if somebody with
expertise in that area reviewed it.

Some of the files are taken from SeaBIOS and are licensed under the GNU
LGPLv3. Is that allowed/wanted to be in libpayload?

Thanks,

Paul
