6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andy Shevchenko andriy.shevchenko@linux.intel.com
commit 2c94512055f362dd789e0f87b8566feeddec83c9 upstream.
This reverts commit d9666dfb314e1ffd6eb9c3c4243fe3e094c047a7.
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.
