7d1b28461e i40e/base: support NVM read on X722
In X722, NVM reads can't be done through SRCTL registers.
And require AQ calls, which require grabbing the NVM lock.
Unfortunately some paths need the lock to be acquired once
and do a whole bunch of stuff and then release it.
This patch creates an unsafe version of the read calls, so
that it can be called from the paths that need the bulk access.

dd59229c8b i40e/base: add flag for X722 register access
Instead of doing the MAC check, use a flag that gets set per
MAC. This way there are less chances of user error and it
can enable multiple MACs with the capability in a single place
rather than cluttering the code with MAC checks.

2427bcaa0a i40e/base: acquire NVM ownership before reading it
SW needs to acquire the NVM ownership before issuing an AQ read
to the X722 NVM otherwise it will get EBUSY from the firmware.
Also it should be released when done.

e31d665baa i40e/base: minor clean up
Use INLINE macro for better cross-platform code management.

Clean up some unnecessary logic jumping and drop a variable.

There was one more __FUNCTION__ reference that wasn't needed.

bd6651c2d2 i40e/base: use bit shift macros
Use macros for abstracting (1 << foo) to BIT(foo)
and (1ULL << foo64) to BIT_ULL(foo64) in order to match
better with linux kernel requirements.

3ed6c3246f i40e/base: handle AQ timeout when releasing NVM
There are some rare cases where the release resource call will return an
admin Q timeout. In these cases the code needs to try to release the
resource again until it succeeds or it times out.

Also add little endian conversion for checksum

f766d82b1e i40e/base: add commands for NVM update
Add a new GetStatus command so that the NVM update tool can query
the current status instead of doing fake write requests to probe for
readiness.
Add a facility to run AQ commands through the nvmupdate utility in order
to allow the update tools to interact with the FW and do special
commands needed for updates and configuration changes.
Add a facility to recover the result of a previously run AQ command.

2d01a42227 i40e/base: add wait states to NVM state machine
This adds wait states to the NVM update state machine to signify when
waiting for an update operation to finish, whether we're in the middle
of a set of Write operations, or we're now idle but waiting.

305f81dbd7 i40e/base: save AQ write back descriptor

descriptor buffer was previously created, this gives it to the AQ command
request to be used to save the results.
