disp: msm: fix dsi debugbus in-mem logging

Browse source 
Update the dump_mem pointer offset while storing the debugbus
data for the second DSI to avoid overwriting to same memory.
As part of the change, register the DSI ctrl with sde_dbg from
ctrl_init directly, instead of debugfs_init to avoid code replication.
