of/fdt: add FDT serial scanning for earlycon
This adds FDT parsing of {linux,}stdout-path to setup an early serial console. Enabling of the early console is triggered with "earlycon" (with no options) on the kernel command line. Platforms must either have fixmap permanent mapping support, have a functioning ioremap when early params are parsed, or explicitly call early_init_dt_scan_chosen_serial from architecture code.
