quark_se: Fix bluetooth UART dependency

Fix c6e27a05 was too aggressive.  It turns out that bluetooth on the
Quark SE boards won't enable it's own UART, because it had always been
enabled.  Apps that don't do it already will be broken.

Enable UART_QMSI_0 whenever BLUETOOTH_H4 is pulled in on this
platform.
