[PATCH v7 6/6] spi: davinci: Simplify using devm_clk_get_enabled()

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

devm_clk_get_enabled() returns the clk already (prepared and) enabled
and the automatically called cleanup cares for disabling (and
unpreparing). So simplify .probe() and .remove() accordingly.
