Subject: serial: copy UART properties of UPF_FIXED_TYPE ports provisioned using early_serial_setup
From: Shmulik Ladkani <shmulik@xxxxxxxxx>
Augment the UPF_FIXED_TYPE logic, which currently applies to UART ports
provisioned using platform_device_register.
The suggested patch applies same logic into 'serial8250_register_ports',
making UART ports provisioned using early_serial_setup inherit their
properties from the uart_config entry.
