ACPI: bus: Fix MFD child automatic modprobe issue 

MFD child devices sharing parent's ACPI Companion fails to probe as
acpi_companion_match() returns incompatible ACPI Companion handle for
binding with the check for pnp.type.backlight added recently. Remove this
pnp.type.backlight check in acpi_companion_match() to fix the automatic
modprobe issue.
