freedreno/a6xx: Document private memory registers

Browse source 
They seem to be broadly similar to the a3xx ones, albeit with some
things shuffled around and with different units, and the extra layout
mode bits.

We also document the FIRST_EXEC_OFFSET registers, so that we can start
properly setting them all to 0 in freedreno and turnip in later commits.
I discovered the compute one when playing with function support in the
blob CL driver, and added the other registers via analogy (the blob
Vulkan driver sets FIRST_EXEC_OFFSET and the shader VA together in one
packet for all stages, so it seems to really be in the same place for
all stages).

Seems to be the same as a3xx. The maximum stack
size in units of 4 calls, so a call depth of 7
would result in a value of 2.
TODO: What's the actual size per call, i.e. the
size of the PC? a3xx docs say it's 16 bits
there, but the length register now takes 28 bits
so it's probably been bumped to 32 bits.

There are four indices used to compute the
private memory location for an access:
- stp/ldp offset
- fiber id
- wavefront id (a swizzled version of what "getwid" returns)
- SP ID (the same as what "getspid" returns)
The stride for the SP ID is always set by
TOTALPVTMEMSIZE. In the per-wave layout, the
indices are used in this order:
- offset % 4 (offset within dword)
- fiber id
- offset / 4
- wavefront id
- SP ID
and the stride for the wavefront ID is
MEMSIZEPERITEM, multiplied by 128 (fibers per
wavefront). In the per-fiber layout, the indices
are used in this order:
- offset
- fiber id % 4
- wavefront id
- fiber id / 4
- SP ID
and the stride for the fiber id/wavefront id
combo is MEMSIZEPERITEM.
Note: Accesses of more than 1 dword do not work
with per-fiber layout. The blob will fall back
to per-wave instead.

This seems to be be the equivalent of HWSTACKOFFSET in
a3xx. The offset formula isn't affected by
HWSTACKOFFSETPERTHREAD at all, so the HW return address
stack seems to be after all the normal per-SP private
memory.
