interrupt-map-mask of 0 implies that all devices are wired to the
same IRQ lines, which is rather unusual. Better leave that open
so the interrupt-map can be written to work on any board.

This string does not match what you use everywhere else. Please fix
either the documentation here or every other instance. The stock
ticker symbol is MOSCHIP.BO, so using "moschip" is probably better
than "moschp".
