Add CONFIG_{SD|NAND|ONENAND|SPI|QSPI|SATA}_BOOT kconfig entries.
SoCs supports loading U-Boot from different medias to DRAM, such as i.MX6/7 supports loading U-Boot to DRAM from sd/emmc/nand/qspi/spi/sata and etc. For i.MX, imximage will generate different IVT headers according to boot medias.

V2: Move NOR_BOOT to the patch 1/2. The idea of this patch is for adding different boot media support for i.MXes. And I'll post out following patches if this patch is accepted. I ran moveconfig.py, but I did not include the results into a patch. This patch does not break the boards which defined NAND_BOOT/SD_BOOT and etc, and I prefer to let board owners to move to defconfig later.
