platform/x86: intel: hid: Always call BTNL ACPI method

On a HP Elite Dragonfly G2 the 0xcc and 0xcd events for SW_TABLET_MODE
are only send after the BTNL ACPI method has been called.

Likely more devices need this, so make the BTNL ACPI method unconditional
instead of only doing it on devices with a 5 button array.

Note this also makes the intel_button_array_enable() call in probe()
unconditional, that function does its own priv->array check. This makes
the intel_button_array_enable() call in probe() consistent with the calls
done on suspend/resume which also rely on the priv->array check inside
the function.
