tty: serial: 8250: add GUID to hard-coded module alias in 8250_dfl driver

[pcolberg]

The DFHv1 GUID needs to match for automatic loading of the driver.

Fixes: 0e524ef ("tty: serial: 8250: Add the GUID definition for UART")

Testing on RHEL 8.10 with Intel N6001 FPGA card.

Without this patch (bf660d8), 8250_dfl driver does not load automatically:

# lsmod | grep 8250
# dmesg | grep tty

With this patch (1ae9844), 8250_dfl driver loads automatically:
