Add support for serial console into the i.MX23/i.MX28 SPL. A full, uncrippled serial console support comes very helpful when debugging various spectacular hardware bringup issues early in the process. Because we do not use SPL framework, but have our own minimalistic SPL, which is compatible with the i.MX23/i.MX28 BootROM, we do not use preloader_console_init(), but instead use a similar function to start the console. Nonetheless, to avoid blowing up the size of the SPL binary, this support is enabled only if CONFIG_SPL_SERIAL_SUPPORT is defined, which is disabled by default.
