spi: uniphier: Simplify clock handling with devm_clk_get_enabled()

[ Upstream commit fdca270f8f87cae2eb5b619234b9dd11a863ce6b ]

Replace devm_clk_get() followed by clk_prepare_enable() with
devm_clk_get_enabled() for the clock. This removes the need for
explicit clock enable and disable calls, as the managed API automatically
handles clock disabling on device removal or probe failure.

Remove the now-unnecessary clk_disable_unprepare() calls from the probe
error path and the remove callback. Adjust error labels accordingly.
