When a stall is detected, the state of each NOCB CPU is dumped along
with the state of each NOCB group. The latter part however is
incidentally ignored if the NOCB group leader happens not to be
offloaded itself.
Fix this to make sure related precious informations aren't lost over
a stall report.

struct virtio_net_rss_config was less useful in actual code because of a
flexible array placed in the middle. Add new structures that split it
into two to avoid having a flexible array in the middle.

Both MT8192 and MT8195 have an L1TCM memory, so it should be described
in reg, and therefore reg's minItems should be 3, as is already implicit
by reg-names. Override minItems to 3 for MT8192 and MT8195.

dual-core SCP")

The SCP is currently described in the Devicetree as a single-core
processor, but really it is a cluster with two cores. Describe the full
cluster but enable only core0 on the current mt8188 platforms since
that's the only one usable with the upstream firmware.

The SCP present on MT8188 does not have an L1TCM memory region, but the
binding incorrectly requires one for the dual-core description of the
MT8188 SCP. Remove that requirement. Also update the minimum number of
reg and reg-names to 1, since as this is a multi-core SCP with no
L1TCM memory, only t
Add the firmware-name property for SCP core0 so the firmware can be
loaded from its canonical location in the linux-firmware repository.
