[PATCH 10/17] spi: slave-mt27xx: Use helper function devm_clk_get_enabled()

[Pei Xiao]

devm_clk_get() and clk_prepare_enable() can now be replaced by
devm_clk_get_enabled() when driver enables the clocks. Moreover, it is no
longer necessary to unprepare and disable the clocks explicitly.
Simplify code.
