   mDisplays' index, so rules for deciding a AVAILABLE_DISPLAY_UNITS's index should be followed.
   - Rules
     1. Display's order is decided by descending order of display type defined in "hwcomposer_defs.h".
     2. If more than two displays have same display type, order is decided by descending order of
        exynos_display_t's index value.
   Scenario affcted by this order is as follows.
   - Scenario
     1. HWC's main API like as validateDisplay and presentDisplay should be called by inverse order of mDisplays' index.
     2. Process for preassigning M2MMPP resources should be called by inverse order of mDisplays' index.
     3. For the process about preassigning OTFMPP resources, display that do not use DPU like as virtual display
        should be alligned at the end. */
