Tegra: support to set the L2 ECC and Parity enable bit

This patch adds capability to read the boot flag to enable L2 ECC
and Parity Protection bit for the Cortex-A57 CPUs. The previous
bootloader sets this flag value for the platform.

* with some coverity fix:
MISRA C-2012 Directive 4.6
MISRA C-2012 Rule 2.5
MISRA C-2012 Rule 10.3
MISRA C-2012 Rule 10.4
