[SeaBIOS] Added ACPI SLIC table

[Arseny Klimovsky]

Hello,
in some cases Microsoft OEM licence can be used in virtual machine legally.

For Windows 7 it is not clear, but possibly it is legal.
To make in technically possible, one should use its ACPI SLIC table from
original BIOS in virtual BIOS.
I've created a patch for some versions (including latest stable), it can
be easily cherry-picked in master.

Of course, the patch does not include this SLIC table, only a code and
place to put it.

Coreboot project have such support (at least for some motherboards).
