spi: cadence-quadspi: Fix probe error path and logging

Merge series from Anurag Dutta <a-dutta@ti.com>:

This series addresses issues in the cadence-quadspi driver's probe
error path:

Patch 1 fixes a clock disable imbalance that occurs when probe fails
after runtime PM is enabled, particularly when DMA request returns
-EPROBE_DEFER.

Patch 2 adds proper error logging for DMA request failures using
dev_err_probe() to improve diagnostics and handle probe deferral
appropriately.
