spi: cadence-quadspi: fix protocol setup for non-1-1-X operations
cqspi_set_protocol() only set the data width, but ignored the command
and address width (except for 8-8-8 DTR ops), leading to corruption of
all transfers using 1-X-X or X-X-X ops. Fix by setting the other two
widths as well.
While we're at it, simplify the code a bit by replacing the
CQSPI_INST_TYPE_* constants with ilog2().
Tested on a TI AM64x with a Macronix MX25U51245G QSPI flash with 1-4-4
read and write operations.
