Subject: MIPS: Fix console output for Fulong2e system

From: Guenter Roeck <linux@roeck-us.net>

commit fc2ca674470bbfe11d72a20a3f19fd3dc43bfca0 upstream.

Commit 3adeb2566b9b ("MIPS: Loongson: Improve LEFI firmware interface")
made the number of UARTs dynamic if LEFI_FIRMWARE_INTERFACE is configured.
Unfortunately, it did not initialize the number of UARTs if
LEFI_FIRMWARE_INTERFACE is not configured. As a result, the Fulong2e
system has no console.
