spi: cadence-quadspi: add missing clk_disable_unprepare() in cqspi_probe()
[ Upstream commit 5cb475174cce1bfedf1025b6e235e2c43d81144f ]
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.
