arm64: dts: exynos7870-j6lte: reduce memory ranges to base amount

Browse Source 
The device is available in multiple variants with differing RAM
capacities. The memory range defined in the 0x80000000 bank exceeds the
address range of the memory controller, which eventually leads to ARM
SError crashes. Reduce the bank size to a value which is available to
all devices.

The bootloader must be responsible for identifying the RAM capacity and
editing the memory node accordingly.
