We want to support 1/8th mode only if both endpoints have enabled
it. To know if each endpt supports 1/8th mode in the core driver,
we added a new field in shared nvlink_link struct.
Initialize this new field to false as dGPU nvlink does not currently
support 1/8th mode.

In nvgpu repository, we have multiple accesses to methods in
pmu_gk20a.h which have register accesses. Instead of directly invoking
these methods, these are now called via HALs. Some common methods such
as pmu_wait_message_cond which donot have any register accesses
are moved to pmu_ipc.c and the method declarations are moved
to pmu.h. Also, changed gm20b_pmu_dbg to
nvgpu_dbg_pmu all across the code base. This would remove all
indirect dependencies via gk20a.h into pmu_gk20a.h. As a result
pmu_gk20a.h is now removed from gk20a.h

This fix violations where an arithmetic operation is performed on

In balloc_get_order_list() the argument "int order" has been changed to

This flag - has_physical_mode - doesn't seem to do much other than
force the PTE/PDE and inst block addresses to be physical instead
of potentially IOMMUed.
There is a reason to do this on volta (nvlink not being IOMMU'able
being the primary reason) but this flag is too general it seems.
The flag was being enabled on all native platforms. The problem is
that some page tables (the maxwell small page directories) could
be larger than 4KB which meant that the allocation used for them
could be potentially discontiguous. Discontiguous page directories
obviously is incorrect.
This patch deletes the has_physical_mode flag and instead replaces
the places where it's checked with a check for nvlink being
enabled. Since we _do_ want to program phyiscal PDEs and PTEs for
NVLINK devices (regardless of IOMMU status they always access
memory by physical address) we need a check for NVLINK state.

The use of the _THIS_IP_ macro in nvgpu introduces two separate
MISRA Rule 11.6 violations.
The first is when when the label address (which gcc generates as
a void *) is cast to an unsigned long and the second is when that
unsigned long is cast back to a void * in the timer and kmem code
that track the value.
Skipping the intermediate use of unsigned long eliminates these
violations. To do this, references to _THIS_IP_ are replaced
with a new (compliant) _NVGPU_GET_IP_ macro.
