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
