[nrf fromtree] boards: nordic: Flatten shared_ramxx_region nodes
Update the default memory maps for `nrf54h20dk` and `nrf9280pdk` to remove the `shared_ram20_region` and `shared_ram3x_region` nodes, because their child nodes no longer need to be grouped together: * IPC buffers in RAM20 are statically allocated. * DMA buffers in RAM3x have separate access owners. Signed-off-by: Grzegorz Swiderski <[email protected]> (cherry picked from commit 85b0394)
