[PATCH 1/1] arm64: dts: tqmls1046a: Move BMAN/QMAN buffers to DRAM1 area

[Alexander Stein]

DRAM1 is only 2GiB in size (0x00_8000_0000 - 0x01_0000_0000) which is
already used by Linux kernel, etc. Move the allocation area of BMAN and
QMAN to DRAM1 region. This frees the complete DRAM2 area for e.g. CMA.

There is a project which needs the upper 2GiB as CMA memory, so these
buffers needs to move. This range also works for 1GiB RAM module
variants.
