We have the i915 security fixes to backmerge, but first
let's clear the decks for other drivers to avoid a bigger
mess.

<title>drm/amdgpu: add dummy read by engines for some GCVM status registers in gfx10</title>

<id>589b64a7e39720b1784a1a26569c57cb977936ef</id>
<content type='text'>
The GRBM register interface is now capable of bursting 1 cycle per
register wr-&gt;wr, wr-&gt;rd much faster than previous muticycle per
transaction done interface.  This has caused a problem where
status registers requiring HW to update have a 1 cycle delay, due
to the register update having to go through GRBM.

For cp ucode, it has realized dummy read in cp firmware.It covers
the use of WAIT_REG_MEM operation 1 case only.So it needs to call
gfx_v10_0_wait_reg_mem in gfx10. Besides it also needs to add warning to
update firmware in case firmware is too old to have function to realize
dummy read in cp firmware.

For sdma ucode, it hasn't realized dummy read in sdma firmware. sdma is
moved to gfxhub in gfx10. So it needs to add dummy read in driver
between amdgpu_ring_emit_wreg and amdgpu_ring_emit_reg_wait for sdma_v5_0.
