ACPI: video: Fix Lenovo Ideapad Z570 DMI match
[ Upstream commit 2d11eae42d52a131f06061015e49dc0f085c5bfc ]
Multiple Ideapad Z570 variants need acpi_backlight=native to force native
use on these pre Windows 8 machines since acpi_video backlight control
does not work here.
The original DMI quirk matches on a product_name of "102434U" but other
variants may have different product_name-s such as e.g. "1024D9U".
Move to checking product_version instead as is more or less standard for
Lenovo DMI quirks for similar reasons.
