A Tegra114 HW bug prevents the main CPU vector from being modified under
certain circumstances. Tegra114 A01P and later with a patched boot ROM
set the CPU reset vector to 0x4003fffc (end of IRAM). This allows placing
an arbitrary jump instruction at that location, in order to redirect to
the desired reset vector location. Modify Tegra114's start_cpu() to make
use of this feature. This allows CPUs with the patched boot ROM to boot.
