This reverts commit d9666dfb31.
The container of the struct dw8250_port_data is private to the actual
driver. In particular, 8250_lpss and 8250_dw use different data types
that are assigned to the UART port private_data. Hence, it must not
be used outside the specific driver.
Fix the mistake made in the past by moving the respective definitions
to the specific driver.
