MISRA Rule-17.7 requires the return value of all functions to be used.
Fix is either to use the return value or change the function to return
void. This patch changes calls to nvgpu_falcon_bootstrap to handle
error codes.

Move code involved in nvlink interrupt and error handling and
initialization into a separate unit under subelement 'nvlink'.
Add g->ops.nvlink.intr_err ops to allow other units to access
the APIs exposed by this unit.

The Tegra SOC nvlink driver and dGPU nvlink driver depend on
struct definitions, macros and functions exposed by nvlink-core
driver. The nvlink-core driver is not part of the nvgpu driver,
hence we should not be directly accessing any core driver
APIs/macros/structs from the /common/nvlink code. Common code can
only use nvgpu internal APIs. We wrap all calls from common/nvlink.c
to other drivers in nvgpu wrappers, and define the implementation of
wrappers in os/linux and os/nvgpu_rmos, and stub them in os/posix.
Also, we remove the implicit inclusion of OS specific nvlink header
file via common nvgpu/nvlink.h. So the OS specific code needs to
explicitly add OS specific header file.

Rename __nvgpu_set_enabled() to nvgpu_set_enabled(). The original
double underscore was present to indicate that this function is a
function with potentially unintended side effects (enabling a feature
has wide ranging impact).
To not lose this documentation a comment was added to convey that this
function must be used with care.

With intention to make falcon header free of private data we are making
all falcon struct members (pmu.flcn, sec2.flcn, fecs_flcn, gpccs_flcn,
nvdec_flcn, minion_flcn, gsp_flcn) in the gk20a, pointers to struct
nvgpu_falcon. Falcon structures are allocated/deallocated by
falcon_sw_init & _free respectively.
While at it, remove duplicate gk20a.pmu_flcn and gk20a.sec2_flcn,
refactor flcn_id assignment and introduce falcon_hal_sw_free.

Move the nvlink HAL code to unit specific directory as part
of nvgpu restructing.
This move is done after removing usage of other unit's hardware
headers from nvlink. Also confirmed that no other unit files are
including nvlink hardware headers.
