tegra124: enable JTAG in Security Mode

Hardware / Coreboot - Jimmy Zhang [nvidia.com] - 12 November 2014 13:16 UTC

Once SECURITY_MODE fuse is burned, JTAG is disabled by default. To reenable JTAG, besides chip unique id and SecureJtagControl need to be built into BCT, Jtag enable flag is also needed to be set.

BUG=None TEST=Burn SECURITY_MODE fuse, build chip specific BCT, coreboot comes up and jtag hooks up fine.
