Tegra: TZDRAM setup from soc specific early_boot handlers
TZDRAM setup is not required for all Tegra SoCs. The previous bootloader
can enable the TZDRAM fence due to architectural improvements in the
newer chips.
This patch moves the TZDRAM setup to early_boot handlers for SoCs to
handle this scenario.
