[PATCH -next 23/25] spi: pic32: Use helper function devm_clk_get_enabled()

[Li Zetao <lizetao1@xxxxxxxxxx>]

Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks"), devm_clk_get() and clk_prepare_enable() can now be
replaced by devm_clk_get_enabled() when driver enables (and possibly
prepares) the clocks for the whole lifetime of the device. Moreover, it is
no longer necessary to unprepare and disable the clocks explicitly.
