Not all SoCs provide all the usual paths. By the looks of it, at least
SM8150 and SM8250 don't have one that would resemble "qup-core".
Check for the error that icc_get throws and assign a NULL value to each
path that can't be found to effectively allow any combination of icc paths
(which, like previously, includes no icc paths). The ICC APIs gracefully
handle a NULL path by exiting early.
