tegra124: enable JTAG in Security Mode
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.
