[PATCH v3 3/4] arm64: dts: rockchip: rk3588: Add JPEG decoder node

[Sascha Hauer <s.hauer@pengutronix.de>]

Add device tree nodes for the Rockchip JPEG hardware decoder and its
IOMMU on the RK3588.

The decoder is at 0xfdb90000 with its MMU at 0xfdb90480.  It takes the
AXI and AHB clocks and resets, and sits in the VDPU power domain.  The
AXI clock is pinned to 600 MHz, which is the rate the downstream BSP
runs it at; it is a dedicated clock, not shared with another block.

Both blocks are entirely on-SoC and have no board dependency, so they are
enabled unconditionally like the other codec blocks in this file.
