ARM: SoC fixes for 6.6, part 2

Browse Source 
AngeloGioacchino Del Regno is stepping in as co-maintainer for the
 MediaTek SoC platform and starts by sending some dts fixes for
 the mt8195 platform that had been pending for a while.
 
 On the ixp4xx platform, Krzysztof Halasa steps down as co-maintainer,
 reflecting that Linus Walleij has been handling this on his own
 for the past few years.
 
 Generic RISC-V kernels are now marked as incompatible with the
 RZ/Five platform that requires custom hacks both for managing
 its DMA bounce buffers and for addressing low virtual memory.
 
 Finally, there is one bugfix for the AMDTEE firmware driver
 to prevent a use-after-free bug.
