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.

Will drop changes to this file and post a new patch.
