arm64: dts: lito: Remove display ramdump memory region



This region is the same as the early splash framebuffer initialized by
XBL. msm_drm uses it for ramdump when available, but that's a debugging
feature we don't need. It also wastes memory after early boot because
msm_drm will keep it reserved rather than freeing the framebuffer memory
once it has taken control of the display hardware.

Remove the display ramdump region to save 35 MiB of memory and silence
the following error on boot:

[    0.000000] OF: reserved mem: OVERLAP DETECTED!\x0adisp_rdump_region (0x00000000a0000000--0x00000000a2300000) overlaps with cont_splash_region (0x00000000a0000000--0x00000000a2300000)
