boards: mimxrt1010_evk: Add Arduino I2C support

When ever a Ardunio UNO R3 compatible shield will be used
together with the NXP MIMXRT1010-EVK board Zephyr runs into
an DTS parse error because of missing label 'arduino_i2c'.

On NXP MIMXRT1010-EVK pin D14 (SDA) and D15 (SCL) will be
shared with multiple on-board components: audio codec and
sensors. Pin A4 (SDA) and A5 (SCL) are not connected in
parallel, but unusually shared with pin D6 (A4) and D7 (A5)
as same signal line. When solder bridge R793 for pin D5
was populated, pin D5 (GPIO/PWM) will be shared with pin
D14 (SDA) and is connected in parallel.
