drm/msm/mdss: Rename path references to mdp_path
[ Upstream commit fabaf176322d687b91a4acf1630c0d0a7d097faa ]
The DPU1 driver needs to handle all MDPn<->DDR paths, as well as
CPU<->SLAVE_DISPLAY_CFG. The former ones share how their values are
calculated, but the latter one has static predefines spanning all SoCs.
In preparation for supporting the CPU<->SLAVE_DISPLAY_CFG path, rename
the path-related struct members to include "mdp_".
