This patch adds the support for gfx90c apu. So far we treat it as "dgpu" and
gfx900. Will update hsa gfxip table while the isa/llvm is implemented on gfx90c.

On NUMA system, allocate queue ctx save restore area on the closest NUMA
node to the GPU which the queue is going to run. This will improve
performance on NUMA system generally by reducing schedule latency and
fix the multi-node rccl-tests unstable performance issue.
If the closest NUMA node has no memory available, set flags NoNUMABind=1
to bypass mbind, to use default NUMA memory policy to allocate system
memory.

on NUMA system, node 0 may have no memory, application pass node id
0 to hsaKmtAllocMemory will fail because mbind to specify the allocation
from node 0 return EINVAL.
Add new flag NoNUMABind for application to pass it to hsaKmtAllocMemory
to skip mbind.
hsaKmtCreateEvent and hsaKmtCreateQueue specify the new flag NoNUMABind
to allocate system memory for event page and CWSR area, don't bind the
system memory to a specific NUMA node.

Originally reserved 100 SGPRs per wave. Pre-gfx10 needs 102 SGPRs
and gfx10 needs 128 SGPRs. Reserve 128 SGPRs per wave for all ASICs
to simplify calculation.
Also double VGPR register size for gfx908 family

queue is the CP and the size is small. Dispatch latency improves
through lower read latency in AQL completion phase.

Marking heap memory as executable using mprotect() is not allowed
by SELinux. mprotect() calls that try to do this will fail on systems
with SELinux enabled. This is also a security risk, so it should be
fixed even on systems that allow this.
Any memory we want to mark as executable must be allocated using mmap().
See https://www.akkadia.org/drepper/selinux-mem.html
The two places where we try to mark heap memory as executable both use
posix_memalign() to allocate the heap memory. In both cases, the
alignment value passed into this function is always equal to PAGE_SIZE,
which means that they are safe to replace with mmap(), which guarantees
alignment to PAGE_SIZE. In this case PAGE_SIZE has been set to
sysconf(_SC_PAGESIZE);
v2:
- Use MAP_PRIVATE instead of MAP_SHARED. This matches the behavior
of memory allocated by posix_memalign()
- Ignore alignment hints instead of returning error when we can't
accommodate them.
- Drop alignment parameter of allocate_exec_aligned_memory() since
the only alignment supported is sysconf(_SC_PAGESIZE).
- Remove extra parameter from fmm_release().
- Add error path to fmm_allocate_host_cpu() for when mmap fails.
v3:
- Avoid use after free.

initialized to the control stack size on all ASICs. MEC microcode
assumes this space is available when the workgroup state offset is
reset after a context restore event.

Use of typedefs/externs/volatile/sscanf
Lines over 80 characters
Remaining errors are due to misunderstanding the * symbol with typedefs

CWSR buffers can be large on dGPUs (~21MB on gfx803). Allocating them
in VRAM limits the number of queues that can be created unnecessarily.
Also make freeing of per-queue buffers symmetric with allocation. All
buffers are now allocated with allocate_exec_aligned_memory on dGPUs
and APUs, so use free_exec_aligned_memory to free them.
