The Seagate Expansion Portable Drive HDD (ext4 file system,
idVendor=0bc2, idProduct=2321) is reported to fail to work
on the rk3399/rk3328 platforms USB 3.0 interface with the
following error message when do read/write operation by dd
command:
xhci-hcd xhci-hcd.11.auto: Ring expansion failed
It's because that xHCI use the dma_pool_alloc() to allocate
DMA buffer for segment_pool with GFP_ATOMIC flag, however,
the default 256 KiB coherent pool is too small for the USB
HDD, so increase it to 1024 KiB to make sure that devices
will be able to allocate their DMA buffers with GFP_ATOMIC
flag.

When playing secure video, you need to interact with secure OS.
The interaction to secureOS must be a physical continuous memory,
so CMA needs to be used, and now CMA is not enough and 32M is
enough.

Some nodes are always used for android, so we move them to android.dtsi.
