gcc-ipq5332 uses DT indices, please don't mix that with .fw_name.

Soo... As you are reverting this. Is USB0 PIPE clock required to be
parked to the XO? I was going to write 'before turning USB0_GDSC' off,
but then I noticed that gcc-ipq5332 doesn't declare GDSCs. Does this
platform have GDSCs?

complete and definitive NAK. Do not use parent_names, we have just
stopped migrating from them.
