Subject: [PATCH] arm64: dts: meson-gx: remove wrong reserved BL31 memory

Kernel boot fail on Khadas VIM1 VIM2 (meson GX) boards
SOLUTION: just remove wrong mem reservation for 0x10000000 0x200000

 ## Booting kernel from Legacy Image at 08080000 ...
   Image Name:   kernel
   Image Type:   AArch64 Linux Kernel Image (lzma compressed)
   Data Size:    4657736 Bytes = 4.4 MiB
   Load Address: 0f080000
   Entry Point:  0f080000
   Verifying Checksum ... OK
 ## Flattened Device Tree blob at 08008000
   Booting using the fdt blob at 0x8008000
   Uncompressing Kernel Image
 ERROR: reserving fdt memory region failed (addr=10000000 size=200000)
