tkudav 3856381b43 gpu: nvgpu: Clear nvlink error persistent state ...

Error logging bits within the nvlink blocks like TLC and MIF are
persistent through reset, to enable them to be polled following
a reset event.  That means that they are in an unknown state at
cold reset, and may contain error state after a warm reset event.
Software is expected to reset them, either by writing ones to the
status bits or by writing to the DEBUG_RESET register at the IOCTRL
top level, to clear the state out before enabling error reporting.
