serial: 8250_mxpcie: introduce per-port private data structure

Browse source

Introduce a private per-port data structure for the mxpcie driver and
replace the shared flexible array of registered lines with an array of
per-port objects.

This prepares the driver for storing per-port state needed by subsequent
features.

No functional change intended.
