serial: 8250_platform: fix uart_8250_port initializer

Browse Source 
The first element in uart_8250_port is a structure, so initializing
it to 0 causes a warning on newer compilers:

drivers/tty/serial/8250/8250_platform.c: In function 'serial8250_platform_probe':
drivers/tty/serial/8250/8250_platform.c:111:40: error: excess elements in struct initializer [-Werror]
  111 |         struct uart_8250_port uart = { 0 };

Use the modern empty {} initializer instead that works on all
supported compilers.
