Maxim Max7357 has a configuration register to enable additional
features. These features aren't enabled by default & its up to
board designer to enable the same as it may have unexpected side effects.
These should be validated for proper functioning & detection of devices
in secondary bus as sometimes it can cause secondary bus being disabled.
Add booleans for:
- maxim,isolate-stuck-channel
- maxim,send-flush-out-sequence
- maxim,preconnection-wiggle-test-enable

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.

Only some of the PCA954x compatible ICs have interrupt
capability, but the binding advertises it on all ICs.
Sync the dt-binding with the driver and only advertise it on:
- nxp,pca9542
- nxp,pca9543
- nxp,pca9544
- nxp,pca9545

Convert the i2c-mux-pca954x binding to DT schema format.
Add the missing compatible for 'nxp,pca9645' which is already in use.
