i40e: use DECLARE_BITMAP for state fields 

Instead of assuming our flags fit within an unsigned long, use
DECLARE_BITMAP which will ensure that we always allocate enough space.
Additionally, use __I40E_STATE_SIZE__ markers as the last element of the
enumeration so that the size of the BITMAP is compile-time assigned
rather than programmer-time assigned. This ensures that potential future
flag additions do not actually overrun the array. This is especially
important as 32bit systems would only have 32bit longs instead of 64bit
longs as we generally have assumed in the prior code.

This change also removes a dereference of the state fields throughout
the code, so it does have a bit of code churn. The conversions were
automated using sed replacements with an alternation

  s/&(vsi->back|vsi|pf)->state/\1->state/
  s/&adapter->vsi.state/adapter->vsi.state/

For debugfs, we modify the printing so that we can display chunks of the
state value on new lines. This ensures that we can print the entire set
of state values. Additionally, we now print them as 08lx to ensure that
they display nicely.
