sfxge(4): report support for Tx checksum op descriptors

FreeBSD driver needs a patch to provide a means for packets
which do not need checksum offload but have flow ID set
to avoid hitting only the first Tx queue (which has been used
for packets not needing checksum offload).

This should be possible on Huntington, Medford or Medford2 chips
since these support toggling checksum offload on any given queue
dynamically by means of pushing option descriptors.

The patch for FreeBSD driver will then need a means to figure out
whether the feature can be used, and testing adapter family might
not be a good solution.

This patch adds a feature bit specifically to indicate support
for checksum option descriptors. The new feature bits may have
more users in future, apart from the mentioned FreeBSD patch.

sfxge(4): add API to inform libefx of hardware removal

The efx_nic_hw_unavailable() checks ensure that if the NIC hardware
has failed or has been physically removed then libefx will stop
further attempts to access the hardware.

Add an interface for libefx clients to force unavailability, so the
hardware is treated as dead or removed even if still physically present.

sfxge(4): fix diagnostics support build without Siena

The compilation failed because __efx_sram_pattern_fns was used in
efx_nic.c, but defined in efx_sram.c which is only needed when
supporting Siena.

To fix it move all the code using __efx_sram_pattern_fns into
Siena-specific files (except for the definition in efx_sram.c itself,
as that file only needs to be included in Siena-supporting builds
anyway).

The functions to test registers and tables are unlikely to apply to any
new hardware and so can be moved into Siena files. Since Huntington
such tests have been implemented in firmware.
