The current code does not properly calculate the indexes within the PDE
to access the proper entry, and it has a bug in assignement of the big
page entries. This change fixes the issue by:
(1) Passing a pointer to the level structure and dereferencing the
index offset to the next level.
(2) Changing the format of the address.
(3) Ensuring big pages are only selected if their address is set.

This patch removes linux dependencies from sim_gk20a.h under
gk20a/sim_gk20a.h. The following changes are made in this patch.
1) Created a linux based structure sim_gk20a_linux that contains a
common sim_gk20a struct inside it. The common struct sim_gk20a doesn't
contain any linux specific structs.
2) The common struct sim_gk20a contains an added function pointer which
is used to invoke gk20a_sim_esc_readl() method.
3) sim_gk20a.c is moved to nvgpu/common/linux along with a new header
sim_gk20a.h that contains the definition of struct sim_gk20a_linux.
4) struct gk20a now contains a pointer of sim_gk20a instead of the
entire object. The memory for this struct is allocated and initialized during
gk20a_init_support() and freed during invocation of
gk20_remove_support().
5) We first obtain the pointer for struct sim_gk20a_linux from the
pointer of sim_gk20a using the container_of method in order to work on
the struct.

Context TSG teardown procedure:
1. Disable scheduling for the engine's runlist via PFIFO_SCHED_DISABLE.
This enables SW to determine whether a context has hung later in the
process: otherwise, ongoing work on the runlist may keep ENG_STATUS from
reaching a steady state.
2. Disable all channels in the TSG being torn down or submit a new runlist
that does not contain the TSG. This is to prevent the TSG from being
rescheduled once scheduling is reenabled in step 6.
3.
a)Initiate a preempt of the TSG by writing NV_PFIFO_PREEMPT
with the TSG's ID and the TYPE set to TSG if TSG id is known else
do 3b
b)Initiate a preempt of the engine by writing the bit associated with its
runlist to NV_PFIFO_RUNLIST_PREEMPT. This allows us to begin the preempt
process prior to doing the slow register reads needed to determine
whether the context has hit any interrupts or is hung. Do not poll
NV_PFIFO_RUNLIST_PREEMPT for the preempt to complete.
4. Check for preempt done
5. If a reset is needed as determined by step 4:
a. Halt the memory interface for the engine (as per the relevant engine
procedure).
b. Reset the engine via PMC_ENABLE.
c. Take the engine out of reset and reinit the engine (as per the relevant
engine procedure)
6. Re-enable scheduling for the engine's runlist via PFIFO_SCHED_ENABLE.
