imx_common: check for bmode Serial Downloader
Before commit 81c4eccb55cc ("imx: mx6: fix USB bmode to use
reserved value") a non-reserved value has been used to trigger
Serial Downloader using bmode. On some boards this value lead to
unreliable bmode command. With the above mentioned commit, U-boot
switched to use [7:4] b0001, which translates to GPR9 0x10 for
Serial Downloader mode. Check for this new bmode and classify it
as Serial Downloader.
