imx_common: introduce serial download protocol boot mode
When starting i.MX SoC's with BOOT_MODE b01, the boot ROM enteres
Serial Downloader mode. However, serial download does not necessarily
means booting from UART. The boot ROM also supports booting from USB.
Create a technology neutral boot mode called SDP (serial download
protocol).
