MISRA rule 10.3 prohibits implicit assigning of u64 to u32. The nvgpu was
assigning the value returned by ARRAY_SIZE which is a u64 to a u32. This
value was then returned in a function defined by gpu_ops.
This patch changes the return type for these gpu_ops to u64 and updates
the functions that implement the functions and lastly the saved value. This
removes the violation in this instance.

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

MISRA Rule 10.4 only allows the usage of arithmetic operations on
operands of the same essential type category.
Adding "U" at the end of the integer literals to have same type of
operands when an arithmetic operation is performed.
This fix violations where an arithmetic operation is performed on
signed and unsigned int types.
In balloc_get_order_list() the argument "int order" has been changed to
a u64 because all callers of this function pass a u64 argument.

The comptag allocates memory based on the available total RAM, which
theoretically should be the MAX physical RAM size however practically
should deduct the part being taken by the running system. Otherwise,
the taken memory part will never get used and wasted.
This change adds a comptag_mem_deduct to each platform and to allow
them to assign the deductible value based on their own use cases so
as to save memory.

Because these values can be used in expressions that require

Since all userspace apps are using 64K pages these days it makes
sense to set the default large page size to 64K. This in turn
causes the PDE coverage field to be set to 64M in the GPU
characteristics field.
While it would therefor be possible to create a VM with a PDE
coverage that's larger than 64M (128M if you set the large
page size to 128K) this will make the defaults work properly.
This in turn fixes a CUDA issue where CUDA tries to determine
the PDE coverage (and correspondingly a minimum alignemnt) from
the characteristics IOCTL.
