Update the device tree to enable `multi-master` mode on I2C buses shared
between the host BMC and the NV module with HMC. This ensures proper bus
arbitration and coordination in multi-master environments, preventing
communication conflicts and improving reliability.

Remove INA238 and INA230 power sensor nodes from the device tree (DTS) due
to incompatibility with the second-source ISL28022, which shares the same
I2C address.
Move the driver probe to userspace to handle sensor dynamically.

Add device tree nodes for the MAX31790 fan controllers on the Power
Distribution Board (PDB). These nodes enable fan speed control and
monitoring, improving thermal management and system reliability.

Add thermal sensor nodes for the IO Mezzanine (IO Mezz) board in the
Catalina platform device tree. These nodes enable temperature monitoring
for the backend NIC, improving thermal management and monitoring
capabilities.

We notice this interrupt pin always keep low, it cause BMC stuck at boot
up until kernel disabling IRQ of this GPIO pin.
Remove the interrupt of GPIOB4 pin from all IOEXP for now to avoid BMC
get stuck.

Add the `i2c-mux-idle-disconnect` property to all i2c-mux nodes to
ensure proper behavior when switching between multiple I2C buses.
This avoids potential confusion caused by device addresses appearing on
multiple buses when they are not actively selected.
