dt-bindings: i2c: Add Maxim MAX735x/MAX736x variants 



Update the pca954x bindings to add support for the Maxim MAX735x/MAX736x
chips. The functionality will be provided by the existing pca954x driver.

For chips that are powered off by default add a regulator called vdd-supply.

description:

  The binding supports NXP PCA954x and PCA984x I2C mux/switch devices.

  The NXP PCA954x and compatible devices are I2C bus

  multiplexer/switches that share the same functionality

  and register layout.

  The devices usually have 4 or 8 child buses, which are

  attached to the parent bus by using the SMBus "Send Byte"

  command.
