fix(stm32mp15-fdts): use interrupts-extended for i2c2

Update SoC DT file STM32MP151 to use interrupts-extended instead of
interrupts for i2c2. This correct a compilation warning:
build/stm32mp1/debug/fdts/stm32mp157c-ev1-bl2.pre.dts:23.3-26:
 Warning (interrupts_property): /soc/i2c@40013000:#interrupt-cells:
  size is (28), expected multiple of 12
