TI: configs: Commonize the boot of different devices

Commonize in the ti_armv7_common.h the boot scripts for USB, MMC and NAND. Each board file can then select which BOOT_TARGETS are applicable for the target board. And any parameters based on that. Finally removed the findfdt from the common file and made this more board specific as omap4_common should not reference panda. This implemenation was adopted from the tegra-common-post.h file.
