[PATCH 12/18] i40e: enhancements of AQ commands and common interfaces

[Helin Zhang <helin.zhang-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

'LE16_TO_CPU' was added in 'i40e_debug_aq()' to support big-endian
and little endian correctly. Fix of determing the PF number was
added for 'i40e_init_shared_code()', which can solve the issue of
PF pass-through. Also enhancements were added for 'i40e_led_get()'
and 'i40e_led_set()'. 'i40e_update_link_info()' was removed and
replaced by 'i40e_aq_get_link_info()' directly.
'i40e_aq_debug_read_register()' was added for reading internal
registers for debug purpose.
