ARM: sunxi: DT: Add stdout-path property
Add UART aliases and stdout-path property for all the Allwinner boards so that we won't have to rely on the bootargs' console= value, while working with legacy bootloaders. While we're at it, also remove the mentions of earlyprintk in the bootargs, that will remove our default bootargs entirely, and allow the kernel to boot on a system even if DEBUG_LL is configured for another system.
