Add the reserved boot mode used in the bmode command for i.MX 6UL and 6ULL as introduced in commit3fd9579085("imx: mx6ull: fix USB bmode for i.MX 6UL and 6ULL"). Also replace BMODE_UART with BMODE_RESERVED, which is more appropriate. Commit96aac843b6("imx: Use IMX6_BMODE_* macros instead of numericals") added macros for boot modes, in the process the reserved boot mode got named BMODE_UART. We use the reserved boot mode in the bmode command to let the boot ROM enter serial downloader recovery mode. But this is only a side effect, the actual boot mode is reserved...
