boards/x86/arduino_101/arduino_101_defconfig currently enables
CONFIG_UART_QMSI_0_HW_FC (HW flow control on UART 0), but doesn't enable
CONFIG_UART_QMSI_0 (the UART itself), which is a direct dependency.
This means CONFIG_UART_QMSI_0_HW_FC remains disabled despite the request
to enable it, and kconfig.py prints a warning.
Enable CONFIG_UART_QMSI_0 in the arduino_101_defconfig.
