ARM: tegra: clean up the common assembly macros into sleep.h There are some common macros for Tegra low-level assembly code. Clean up them into one header file and move the definitions that will be re-used into it as well.

ARM: tegra: rework Tegra secondary CPU core bringup Prepare the Tegra secondary CPU core bringup code for other Tegra variants. The reset handler is also generalized to allow for future introduction of powersaving modes which turn off the CPU cores.

ARM: tegra: make device can run on UP The reset handler code is used for either UP or SMP. To make Tegra device can compile for UP. It needs to be moved to another file that is not SMP only. This is because the reset handler also be needed by CPU idle "powered-down" mode. So we also need to put the reset handler init function in non-SMP only and init them always. And currently the implementation of the reset handler to know which CPU is OK to bring up was identital with "cpu_present_mask". But the "cpu_present_mask" did not initialize yet when the reset handler init function was moved to init early function. We use the "cpu_possible_mask" to replace "cpu_present_mask". Then it can work on both UP and SMP case.
