Rather than ignoring _cdns_enable_interrupt - despite said func always 
returning 0 - simply do: return _cnds_enable_interrupt(cdns) and flag 
caller with inline.

Afterwards, one can think if such encapsulation is even required - 
remove existing sdw_cdns_enable_interrupt and rename _cnds_enable_interrupt?
