[PATCH] spi: cadence-quadspi: add missing clk_disable_unprepare() in cqspi_probe()

[Yang Yingliang <yangyingliang@xxxxxxxxxx>]

cqspi_jh7110_clk_init() is called after clk_prepare_enable(cqspi->clk),
if it fails, it should goto label 'probe_reset_failed' to disable
cqspi->clk.

In the error path after calling cqspi_jh7110_clk_init(),
cqspi_jh7110_disable_clk() need be called.

Fixes: 33f1ef6d4eb6 ("spi: cadence-quadspi: Add clock configuration for StarFive JH7110 QSPI")
