Subject: [PATCH v4 6/8] ARM: tegra: Always boot CPU in ARM-mode

CPU always jumps into reset handler in ARM-mode from the Trusted
Foundations firmware, hence let's make CPU to always jump into kernel
in ARM-mode regardless of the firmware presence. This is required to
make Thumb-2 kernel working with the Trusted Foundations firmware on
Tegra30.
