[Fix PATCH] ACPI / video: ignore BIOS initial backlight value for Fujitsu E753

[tianyu.lan@intel.com]

From: Lan Tianyu <tianyu.lan@intel.com>

The BIOS of FUjitsu E753 reports an incorrect initial backlight value
for WIN8 compatible OS, causing backlight dark during startup. This
patch ignores the incorrect initial value from BIOS.
