ARM: zynq: Reserve correct amount of non-DMA RAM
commit 7a3cc2a7b2c723aa552028f4e66841cec183756d upstream.
On Zynq, we haven't been reserving the correct amount of DMA-incapable
RAM to keep DMA away from it (per the Zynq TRM Section 4.1, it should be
the first 512k). In older kernels, this was masked by the
memblock_reserve call in arm_memblock_init(). Now, reserve the correct
amount excplicitly rather than relying on swapper_pg_dir, which is an
address and not a size anyway.
Fixes: 46f5b96 ("ARM: zynq: Reserve not DMAable space in front of the kernel")
