interconnect: qcom: Build icc-rpmh with qnoc-lahaina

Commit 342ec64e ("icc: qcom: Refactor icc rpmh support") made
icc-rpmh.c buildable as a module but it isn't set up to be a module which
results in the following warning:

 WARNING: modpost: missing MODULE_LICENSE() in drivers/interconnect/qcom/icc-rpmh.o

It looks like the intent is to make the symbols available in a module but
since only qnoc-lahaina selects it it makes sense for now to put the object
file into that module for now.
