[U-Boot] [PATCH] configs: Lower Lamobo R1 DRAM clock rate to 384 MHz

When running at 432 MHz, the Lamobo R1 DRAM tends to get corrupted under stressing workloads. Reducing the clock rate to 384 MHz results in significantly-improved stability.

One reliable way to trigger a corruption at 432 MHz is to run I/O-intensive operations on an attached SATA disk. The same operations when operating the DRAM at 384 MHz typically go fine.

For some unexplained reason, running at 408 MHz worsens the situation.
