[ Upstream commit e3ab18de2b09361d6f0e4aafb9cfd6d002ce43a1 ]
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.
