Subject: [PATCH V2] spi: cadence-quadspi: use macro DEFINE_SIMPLE_DEV_PM_OPS

Using this macro makes the code more readable.
It also inits the members of dev_pm_ops in the following manner
without us explicitly needing to:

.suspend = cqspi_suspend, \
.resume = cqspi_resume, \
.freeze = cqspi_suspend, \
.thaw = cqspi_resume, \
.poweroff = cqspi_suspend, \
.restore = cqspi_resume
