net: ipa: fix GENERIC_CMD register field masks for IPA v5.0+

[ Upstream commit 9709b56d908acc120fe8b4ae250b3c9d749ea832 ]

Fix the field masks to match the hardware layout documented in
downstream GSI (GSI_V3_0_EE_n_GSI_EE_GENERIC_CMD_*).

Notably this fixes a WARN I was seeing when I tried to send "stop"
to the MPSS remoteproc while IPA was up.
