There is no need to unlock MMIO access to the DBGLAR all the time. Doing so may even cause problems if a SW bug causes writes to that MMIO region. Cortex-A15 processors do not support the CP14 register write the code currently uses to unlock the DBGLAR; the instruction throws an undefined instruction exceptions. This prevents tegra_secondary_startup() from executing on Tegra114, and hence prevents SMP. Remove the code that unlocks this access.
