spi: microchip-core-qspi: Use helper function devm_clk_get_enabled() 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.

spi: microchip-core-qspi: Convert to platform remove callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
