Subject: [PATCH] arm64: dts: imx8qxp: shrink dsp reserved memory

From: Laurentiu Mihalcea <laurentiu.mihalcea@....com>

Shrink the size of the memory reserved for the dsp to half of its original
size to avoid an overlap with the 'dsp_vdev0vring0' memory region. 16MB of
reserved memory should be enough anyways.
