arm: tegra: cardhu: Disable ACCELIRQ
Setting MPU_ACCEL_IRQ_GPIO to 0. This helps prevent creation of
device node /dev/accelirq and enable timerirq to provide polling
ticks for the MPU sensors. The MPU sensors are not currently
operating in interrupt mode, the sensors needs to be polled at
regular interval. MPU sensor HAL enables the polling timer in
the absense of /dev/accelirq device node.
