671f126978 net/i40e/base: sync nvmupdate command and adminq subtask
During NVMupdate, state machine gets into unrecoverable state because
i40e_clean_adminq_subtask can get scheduled after the admin queue
command but before other state variables are updated.

This patch adds locking around admin queue command and update of
state variables so that adminq_subtask will have accurate information
whenever it gets scheduled.

5a2e46a3e4 net/i40e/base: refactor NVM update command processing
This patch refactors the NVM update command processing, with adding
a new element of nvm_wait_opcode in struct i40e_hw to indicate
the opcode it waits on, and putting the wait event check into
a function. In addition, that element needs to be initialized
or updated properly.

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.
