The qn9080dk includes a MMA8652FC chip connected to the I2C0 bus, this
patch adds the driver for the in the default.
Note that the MMA8652FC device is powered from the LPC_VCC line, which
is different from the QN_VCC line that powers the QN9080 MCU. A voltage
level translator is included in the QN9080DK which is only enabled when
JP11 (labeled "G-Sensor I2C") is closed and the LPC debugger hardware
is powered, for example from the USB port.
The QN9080DK is the developer board reference from NXP for the QN908x
CPUs. The developer kit comes with two boards: a larger PCB with many
peripherals and a much smaller "USB dongle". This board adds initial
support for the larger "DK board". At the moment, with the minimal CPU
support this board only configures the GPIOs available in the board,
namely the RGB LED and the two user buttons.
