ARM: tegra: Redesign Tegra CPU reset handling
- Add a single unified handler for all CPU resets that is copied to
IRAM.
- Add state information to direct the flow of execution through the
reset handler based on the reason a CPU was reset.
- Write the EVP CPU reset vector only once per cold/warm boot session.
- Prevent modification of the EVP CPU reset vector in Tegra3.
