Remove support for NVGPU_AS_IOCTL_MAP_BUFFER. It has been superseded

Remove legacy definitions to nvgpu_map_buffer_args and the related

-Power features should be enabled only if s/w flags xxcg_enabled
are set for corresponding features. These flags control whether
feature should be kept disabled in the hardware or not. For disable
case, register programming will happen for CG registers
and they will be set to disabled. For ELPG, init command will be
sent to PMU, but “ELPG_ALLOW” will not be sent to PMU.
Also these flags can be modified using sysfs. These flags
are noop if corresponding can_xxxg flags are set to flase.
S/w flags can_xxxg tell the ability of platform to support
a power feature and cannot be modified by syfs. Setting these
flags to false will avoid any HW register write or init sequence
for the power feature from executing. For ELPG, no commands will
be sent to PMU.
-g->elcg_enabled flag should not be modified here.
It should be modified only by sysfs. This will be cleaned up in
follow up implementation where debug session will have some kind
of lock where it will keep power features disabled as long as it
wants to. Debugger cannot rely on this flag to keep power
management disabled as these flags can be changed from sysfs.
Due to this issue someone can easily break debugging session
by accidentally changing something in sysfs.
Proper fix for this is being tracked in NVGPU-320

However, if the graphics context has been allocated from vidmem,
cpu_va is always 0, so we can't tell if nvgpu_mem_begin() was called
for the context buffer or not.
Instead:
- add a cpu_accessible flag to the nvgpu_mem struct and set

- return the value of that flag in nvgpu_mem_cpu_accessible()
- gr_gk20a_ctx_patch_write_begin() now calls this new function

Remove the always true field 'user_mapped' from the mapped_buf
struct. All mapped_bufs are mapped by a user request since they
always originate from a dma_buf (for Linux, that is). As such
there is a fair amount of logic that could be deleted.
Linux specific: the own_mem_ref field was also be deleted. The
logic of only storing a dma_buf ref when the buffer is mapped
for the first time by a user is easy: when the mapped buffer is
found in the map cache release the outstanding dma_buf ref taken
earlier on in the map path. If the map cache does not have the
buffer simply let the higher level map code keep the dma_buf ref.
The dma_buf ref is released when the nvgpu_vm_unmap_system()
call-back is called by the unmap path.
