[PATCH v2] MIPS: Fix console output for Fulong2e system

From: Guenter Roeck
Date: Mon Aug 31 2015 - 00:20:13 EST

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.

Fixes: 3adeb2566b9b ("MIPS: Loongson: Improve LEFI firmware interface")
