[PATCH 2/3] clk: ignore -EPROTO in clk_get_enabled_if_available

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Getting an SCMI clock can succeed with failure being postponed until the
driver attempts to enable the clock, at which time -EPROTO is returned.

Have clk_get_enabled_if_available() ignore that error code after
printing the warning, so the system can at least reach a shell.
