spi: cadence-quadspi: Fix clock disable on probe failure path
When cqspi_request_mmap_dma() returns -EPROBE_DEFER after runtime PM
is enabled, the error path calls clk_disable_unprepare() on an already
disabled clock, causing an imbalance.
Use pm_runtime_get_sync() to increment the usage counter and resume the
device. This prevents runtime_suspend() from being invoked and causing
a double clock disable.
