thermal/drivers/cxgb4: Use generic thermal_zone_get_trip() function

The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.

Convert ops content logic into generic trip points and register them with the
thermal zone.

was applied to net-next when it should have been applied to the PCI tree
because of build errors. However, commit 82e34c8a9bdf ("Revert "Revert
"cxgb4: Search VPD with pci_vpd_find_ro_info_keyword()""") reapplied a
change, resulting in the warning above.

Properly revert commit 8d63ee602da3 ("cxgb4: Search VPD with

cxgb4/ch_ktls: creating skbs causes panic

Creating SKB per tls record and freeing the original one causes
panic. There will be race if connection reset is requested. By
freeing original skb, refcnt will be decremented and that means,
there is no pending record to send, and so tls_dev_del will be
requested in control path while SKB of related connection is in
queue.
Better approach is to use same SKB to send one record (partial
data) at a time. We still have to create a new SKB when partial
last part of a record is requested.
This fix introduces new API cxgb4_write_partial_sgl() to send
partial part of skb. Present cxgb4_write_sgl can only provide
feasibility to start from an offset which limits to header only
and it can write sgls for the whole skb len. But this new API
will help in both. It can start from any offset and can end
writing in middle of the skb.

v4->v5:
- Removed extra changes.

The packet goes until the Multi Port Switch (MPS) just before
the MAC and based on the specified channel number, it either
goes outside the wire on one of the physical ports or looped
back to Rx path by MPS. In this case, we're specifying loopback
channel, instead of physical ports, so the packet gets looped
back to Rx path, instead of getting transmitted on the wire.
