qcacld-3.0: Replace hdd_psoc with psoc

The name 'hdd_psoc' is misleading, since it is not actually an HDD psoc
context. Rather, it is the Object Manager psoc context. Rename hdd_psoc
to psoc for consistency, and to make room for HDD to have its own psoc
context.

After the introduction of hdd_context.psoc in
I9971c478c0d1dc111bb20a7cd6614f73ffb0b15d, replace more instances of
hdd_psoc with psoc.
