tests: drivers: mspi_with_spis: Fix ranges property in sqspi overlay

This is a follow-up to commit c960096
("samples: update according to new nrf54h20 RAM memory map").

After the changes applied by the above commit, the `softperiph_ram`
node can no longer use empty `ranges` property, since its base address
is not 0 now. Add proper address translation, so that the `sqspi` node
base address is correct (not 0x3e00, what results in a bus fault when
the sQSPI is initialized).

Also correct the sQSPI MSPI shim driver documentation accordingly
(apart from correcting the `ranges` property for nRF54H20, restore
properties that were incorrectly removed from the `reserved-memory`
node for nRF54L15).
