     Kconfig: Enable FIT support by default for TI platforms

     Almost all TI defconfigs enable this already, add this as a default
     and remove the explicit assignment.

broke boot on Beagleboard xM. I mean the board hangs after:
     OMAP3630/3730-GP ES1.1, CPU-OPP2, L3-200MHz, Max CPU Clock 800 MHz
     OMAP3 Beagle board + LPDDR/NAND
     I2C:   ready
     DRAM:  512 MiB


To get back the board booting, I need to manually disable FIT (CONFIG_FIT) _and_ disable SHA256 hash support (CONFIG_SHA256).

If I enable FIT without sha256 : it breaks boot.
If I enable sha256 without FIT : it breaks boot.

Any idea what could cause this?

As a workaround we could disable it in the omap3_beagle_defconfig but I guess it would be better to fix it instead of workaround it, since other boards may also be affected.
