[PATCH] spi: orion: use devm_clk_get_optional_enabled for axi clock

[Rosen Penev <rosenp@gmail.com>]

Replace the open-coded optional axi clock get/prepare/enable and the
manual cleanup in probe/remove/runtime_resume with the managed helper
devm_clk_get_optional_enabled(). This removes the now-unused
out_rel_axi_clk error path and simplifies the clock lifecycle.
