platform/x86: dell-smbios-base: Extends support to Alienware products

[ Upstream commit a36b8b84ac4327b90ef5a22bc97cc96a92073330 ]

Fixes the following error:

dell_smbios: Unable to run on non-Dell system

Which is triggered after dell-wmi driver fails to initialize on
Alienware systems, as it depends on dell-smbios.

This effectively extends dell-wmi, dell-smbios and dcdbas support to
Alienware devices, that might share some features of the SMBIOS intereface
calling interface with other Dell products.

Tested on an Alienware X15 R1.
