[U-Boot] [PATCH] common: add new boot media kconfig entry

[Peng Fan]

Add CONFIG_{SD|NOR|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.
