dt-bindings: mfd: qnap,ts433-mcu: Add qnap,ts133-mcu compatible

The same MCU is used on a number of devices, each with a slightly
different set of features, like the number of LEDs.

Add a compatible for the MCU used in the TS133 variant.
This is the 1-disk consumer variant of the RK356x-based family.
