Subject: [PATCH v4 4/5] ARM: dts: imx5: add gpu nodes

This adds the gpu nodes for the adreno 200 GPU on iMX51 and iMX53, now
supported by the freedreno driver.

The compatible for the iMX51 uses a patchid of 1, which is used by drm/msm
driver to identify the smaller 128KiB GMEM size.

v4:
 added commit message
 moved to follow address order
 removed frequencies, they are not needed as clocks have fixed rate
