[PATCH] soc: imx8m: Fix error handling for clk_prepare_enable()

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

imx8m_soc_prepare() directly returns the result of clk_prepare_enable(),
which skips proper cleanup if the clock enable fails. Check the return
value of clk_prepare_enable() and release resources if failure.
