    kernel: modules: fix mlxreg dependency to avoid deferred probe
    
    The mlxreg-hotplug platform driver was failing to probe due to a missing
    I²C multiplexer dependency. Previously, only kmod-i2c-mux-mlxcpld was
    declared, but mlxreg also requires kmod-i2c-mux-reg to initialize its
    I²C mux functionality.
    
    Without this dependency, the driver probe was deferred:
    
      [   24.902331] platform mlxreg-hotplug: deferred probe pending: (reason unknown)
    
    With kmod-i2c-mux-reg added, the probe succeeds and the expected
    multiplexed I²C buses are registered:
    
      [   15.793884] i2c i2c-1: Added multiplexed i2c bus 2
      [   15.799391] i2c i2c-1: Added multiplexed i2c bus 3
      [   15.804830] i2c i2c-1: Added multiplexed i2c bus 4
      ...
