drm/msm/dpu: add wb_idx to existing DRM prints in dpu_encoder

Add wb_idx to existing DRM prints in dpu_encoder and also
print the intf_mode so that its clear that for any INTF_CMD/VID
there will be a valid intf_idx and any INTF_WB_* there will be a
valid wb_idx.

Update the debugfs to add the same information. Here is a sample
output with this change:

root:/sys/kernel/debug/dri/0/encoder31# cat status
intf:1  wb:-1  vsync: 31  underrun: 0    mode: INTF_MODE_VIDEO
root:/sys/kernel/debug/dri/0/encoder33# cat status
intf:-1  wb:2  vsync:  7  underrun: 0    mode: INTF_MODE_WB_LINE

Also remove DPU_DEBUG_PHYS macros as its unused because the
respective dpu_encoder_phys_* files have their own macros.

changes in v2:
	- use switch case instead of if/else-if for get_intf_type
