PCI/pwrctrl: tc9563: Take i2c adapter module reference

Browse source

The i2c subsystem currently blocks during adapter deregistration whenever
there are consumers holding a reference.

Switch to using of_get_i2c_adapter_by_node() which also takes a reference
to the adapter module so that an attempt to unload the module while in use
fails gracefully instead of blocking uninterruptibly.
