platform/x86: asus-wmi: Only Tell EC the OS will handle display hotkeys from asus_nb_wmi 

Commit 78f3ac76d9 ("platform/x86: asus-wmi: Tell the EC the OS will
handle the display off hotkey") causes the backlight to be permanently off
on various EeePC laptop models using the eeepc-wmi driver (Asus EeePC
1015BX, Asus EeePC 1025C).

The asus_wmi_set_devstate(ASUS_WMI_DEVID_BACKLIGHT, 2, NULL) call added
by that commit is made conditional in this commit and only enabled in
the quirk_entry structs in the asus-nb-wmi driver fixing the broken
display / backlight on various EeePC laptop models.
