[PATCH 2/2] spi: cadence-quadspi: allow operations with cmd/addr buswidth >1

[Matthias Schiffer <matthias.schiffer@xxxxxxxxxxxxxxx>]

With the improved cqspi_set_protocol(), ops with cmd/addr
buswidth >1 are now working correctly.

Tested on a TI AM64x with a Macronix MX25U51245G QSPI flash using 1-4-4
operations.

DTR operations are currently untested, so we leave them disabled for now
(except for the previosly allowed 8-8-8 ops).
