Support only VM pointers and ref-counting for maintaining VMs. This
dramatically reduces the complexity of the APIs, avoids the API
abuse that has existed, and ensures that future VM usage is
consistent with current usage.
Also remove the combined VM free/instance block deletion. Any place
where this was done is now replaced with an explict free of the
instance block and a nvgpu_vm_put().

Use platform agnostic delay functions instead of Linux kernel APIs.
This allows removing dependency to Linux header linux/delay.h. At the
same time remove #include lines for other unused Linux headers.

gk20a_err() and gk20a_warn() require a struct device pointer,
which is not portable across operating systems. The new nvgpu_err()
and nvgpu_warn() macros take struct gk20a pointer. Convert code
to use the more portable macros.

Rename the nvgpu DMA APIs from gk20a_gmmu_alloc* to nvgpu_dma_alloc*.
This better reflects the purpose of the APIs (to allocate DMA suitable
memory) and avoids confusion with GMMU related code.

Make an nvgpu DMA API include file so that the intricacies of the
Linux DMA API can be hidden from the calling code.
Also document the nvgpu DMA API.

Move the gp10b HW headers to a new directory specially for them:
include/nvgpu/hw/gp10b
And change the code to include like so:
#include <nvgpu/hw/gp10b/hw_fb_gp10b.h>
This is part of the process to restructure the nvgpu driver.

For devices that have vidmem available, use the vidmem allocator in
gk20a_gmmu_alloc{,attr,_map,_map_attr}. For others, use sysmem.
Because all of the buffers haven't been tested to work in vidmem yet,
rename calls to gk20a_gmmu_alloc{,attr,_map,_map_attr} to have _sys at
the end to declare explicitly that vidmem is used. Enabling vidmem for
each now is a matter of removing "_sys" from the function call.
