[PATCH] i2c: amd8111: Switch to pcim_enable_device() and pcim_request_region()

["Filippo Muscherà" <filippo.muschera@gmail.com>]

Following the conversion to managed devm_* APIs, update the driver to use
the PCI-specific managed APIs.

Use pcim_enable_device() to properly enable the PCI device and
pcim_request_region() to manage the I/O port region.

Switching to pcim_enable_device() also addresses the fact that
pci_disable_device() was  missing in the driver lifecycle, as the
managed API now automatically handles the disablement when the driver
unbinds.
