From: Colin Ian King <redacted>

Static analysis by cppcheck found an issue that was recently introduced by
commit 471f7707b6f0b1 ("PM / clock_ops: make __pm_clk_enable more generic")
where a return status in ret was not being initialised and garbage
being returned when ce->status >= PCE_STATUS_ERROR.

The fact that ret is not being checked by the caller and that
ret is only used internally __pm_clk_enable to check if clk_enable
was OK means we can ignore returning it instead turn
__pm_clk_enable into function with a void return.

Fixes: 471f7707b6f0b1 ("PM / clock_ops: make __pm_clk_enable more generic")
