As suggested, this removes the whole cqspi_set_protocol() function, as it
is not actually needed:
- Checks for unsupported operations are already handled by supports_op(),
removing the need to distinguish DTR and non-DTR modes in the buswidth
setup
- supports_op() ensures that the DTR flags match for all relevant parts of
an operation, so op->cmd.dtr can be used instead of copying the flag to
the cqspi_flash_pdata
- The logic in cqspi_set_protocol() is moved to cqspi_calc_rdreg() and
cqspi_write_setup() (with a helper macro CQSPI_OP_WIDTH())
The helper macro checks nbytes instead of buswidth for 0, for consistency
with supports_op() etc.
