In gfx_v12_0_cp_gfx_load_me_microcode_rs64(), gfx_v12_0_pfp_fini() is
incorrectly used to free 'me' field of 'gfx', since gfx_v12_0_pfp_fini()
can only release 'pfp' field of 'gfx'. The release function of 'me' field
should be gfx_v12_0_me_fini().

Do you care for an imperative wording in such a change description?
