Subject: drm/amd/amdgpu: Update debugfs for XCC support (v3)
This patch updates the 'regs2' interface for MMIO
registers to add a new IOCTL command for a 'v2' state
data that includes the XCC ID.
This patch then updates amdgpu_gfx_select_se_sh()
and amdgpu_gfx_select_me_pipe_q() (and the implementations
in the gfx drivers) to support an additional parameter.
This patch then creates a new debugfs interface "gprwave"
which is a merge of shader GPR and wave status access. This
new inteface uses an IOCTL to select banks as well as XCC identity.
(v2) Fix missing xcc_id in wave_ind function
(v3) Fix pm runtime calls and mutex locking
(v4) Fix bad label
