sfxge(4): add accessor to whole link status

Add a function which makes an MCDI GET_LINK request and
packages up the results. Currently, the get-link function
is triggered from several entry points which then pass
on or store selected parts of the data. When the driver
needs to obtain the current link state, it is more
efficient to do this in a single call.

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): generalise EF10 NVRAM buffer interface

The SFN driver's PartitionControl WMI object requires an API to parse
and filter partition data in TLV format, particularly for the Dynamic
Config partition. The ef10_nvram_buffer functions provide this
functionality but are tied to use with license partition only.
Modify functions so they are applicable to all TLV partitions and add
functions to support in-place tag modification.

sfxge(4): support equal stride super-buffer Rx mode

Equal stride super-buffer Rx mode is supported by DPDK firmware
variant. One Rx descriptor provides many Rx buffers to firmware.
Rx buffers follow each other with specified stride.
Also it supports head of line blocking with timeout to address
drops when no Rx descriptors are available. So it gives extra time
to the driver to provide Rx descriptors before drop.

sfxge(4): support runtime VI window size

Medford2 uses a configurable VI window size, and requires
updates to register accesses to use a runtime VI window size
rather than the *_STEP register constants used for earlier
controllers.

Update the common code to query the VI window size via MCDI,
and add new EFX_BAR_VI_* accessor macros for per-VI registers.

The existing EFX_BAR_TBL_* macros can be used for non-VI
register tables (and for code that can never be called for
a Medford2 controller e.g. Siena-only code).
