[PATCH net-next v4 2/3] stmmac: Remove pcim_* functions for driver detach

[Philipp Stanner]

Functions prefixed with "pcim_" are managed devres functions which
perform automatic cleanup once the driver unloads. It is, thus, not
necessary to call any cleanup functions in remove() callbacks.

Remove the pcim_ cleanup function calls in the remove() callbacks.
