Subject: [PATCH] MIPS: Fix console output for Fulong2e system
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")
