MIPS: generic/yamon-dt: Use serial* rather than uart* aliases
Name aliases in the SEAD-3 device tree serial0 & serial1, rather than uart0 & uart1. This allows the core serial code to make use of the aliases to ensure that the UARTs are consistently numbered as expected rather than having the numbering depend upon probe order. When translating YAMON-provided serial configuration to a device tree stdout-path property adjust accordingly, such that we continue to reference a valid alias.
