[PATCH] remoteproc: imx_rproc: replace devm_clk_get() with devm_clk_get_optional()

[Hiago De Franco]

From: Hiago De Franco <hiago.franco at toradex.com>

The "clocks" device tree property is not mandatory, and if not provided
Linux will shut down the remote processor power domain during boot if it
is not present, even if it is running (e.g. it was started by U-Boot's
bootaux command).

Use the optional devm_clk_get instead.
