Subject: [for next][PATCH v3 2/2] platform/x86: Fix unmet dependency warning for SAMSUNG_Q10

Add BACKLIGHT_LCD_SUPPORT for SAMSUNG_Q10 to fix the
warning: unmet direct dependencies detected for BACKLIGHT_CLASS_DEVICE.

SAMSUNG_Q10 selects BACKLIGHT_CLASS_DEVICE but BACKLIGHT_CLASS_DEVICE
depends on BACKLIGHT_LCD_SUPPORT.

Copy BACKLIGHT_LCD_SUPPORT dependency into SAMSUNG_Q10 to fix:

WARNING: unmet direct dependencies detected for BACKLIGHT_CLASS_DEVICE
  Depends on [n]: HAS_IOMEM [=y] && BACKLIGHT_LCD_SUPPORT [=n]
  Selected by [y]:
  - SAMSUNG_Q10 [=y] && X86 [=y] && X86_PLATFORM_DEVICES [=y] && ACPI [=y]
