dt-bindings: i2c-mpc: Document interrupt property as required
All of the in-tree device-trees that use the one of the compatible strings from i2c-mpc.c supply an interrupts property. Make this property mandatory to aid refactoring the driver.

compatible processor, e.g. mpc8313, mpc8543, mpc8544, mpc5121,
mpc5200 or mpc5200b. For the mpc5121, an additional node
"fsl,mpc5121-i2c-ctrl" is required as shown in the example below.

-Recommended properties :
-
- interrupts : <a b> where a is the interrupt number and b is a
field that represents an encoding of the sense and level
information for the interrupt. This should be encoded based on
the information in section 2) depending on the type of interrupt
controller you have.

- fsl,preserve-clocking : boolean; if defined, the clock settings
from the bootloader are preserved (not touched).
- clock-frequency : desired I2C bus clock frequency in Hz.
