spi: spi-qpic-snand: simplify clock handling by using devm_clk_get_enabled()

The devm_clk_get_enabled() function prepares and enables the
particular clock, which then automatically gets disabled and
unprepared on probe failure and on device removal.

Use that function instead of devm_clk_get() and remove the
clk_prepare_enable()/clk_disable_unprepare() calls in order
to simplify the code.

This also ensures that the clocks are handled in the correct
order during device removal.
