ARC: [plat-eznps] set default baud for early console
For CONFIG_SERIAL_EARLYCON we need 800MHz for NPS SoC The early console driver uses BASE_BAUD and not using dtb. The default of 50MHz is NOT good for NPS SoC. Signed-off-by: Noam Camus <noamca@mellanox.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
