[PATCH] ARM: dts: i.MX8MP: remove now unneeded DSP reserved mem override

[PATCH] ARM: dts: i.MX8MP: remove now unneeded DSP reserved mem override

[Ahmad Fatoum]

The upstream device tree described a dsp_reserved reserved memory entry
at address 0x9240_0000, which could collide with barebox malloc area in
some configurations.

This node has now been disabled upstream in commit 010dc015b811
("arm64: dts: imx8mp: Disable dsp reserved memory by default"), so we
can simplify our DT a bit by dropping the override.

Device trees that make use of the dsp node will now need to override
it on a barebox board DT level.
