i2c: mchp-pci1xxxx: Avoid cast to incompatible function type

Rather than casting pci1xxxx_i2c_shutdown to an incompatible function type,
update the type to match that expected by __devm_add_action.

Reported by clang-16 with W-1:

 .../i2c-mchp-pci1xxxx.c:1159:29: error: cast from 'void (*)(struct pci1xxxx_i2c *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
         ret = devm_add_action(dev, (void (*)(void *))pci1xxxx_i2c_shutdown, i2c);
                                    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 ./include/linux/device.h:251:29: note: expanded from macro 'devm_add_action'
         __devm_add_action(release, action, data, #action)
                                   ^~~~~~

No functional change intended.
Compile tested only.
