arm/fdt: Initial reorg of fdt support code * Makes FDT support code useable by everyone without all of the externs * Further movement to be non-u-boot centic may still happen.

loader/u-boot: Use FDT serial info to create uart * drop my fdt tests * we have to call fdt parsing code *after* cpu_init (why?) * pass fdt pointer to all FDT support calls to avoid confusion once we get into the kernel land * look for PL011 compatible uart and use it * Add some saftey checks to serial putc code to avoid null* * fdt_node_check_compatible returns 0 on success not 1 * fdt_get_device_reg needs to add the SOC base to the result * fdt_get_device_reg might need to add the second range cell instead of reg?
