The SPMI bus has grown additional responsibilities in the M3
generation, making the current driver insufficient. Add M3 comatibles,
support for slave-sent interrupts, FIFO interrupts, power management
commands, parity validation, and fix locking.
To simplify the merge strategy, the device tree entries will be sent
in a future patch series.
