To implement a FW workaround for LFC, a set_local_mib must be
performed after every link up event. For systems that do not
have DCB configured, we need to move the function
ice_aq_set_lldp_mib() from the DCB specific ice_dcb.c to
ice_common.c so that the driver always has access to this AQ
command.

The current implementation for reading device and function capabilities
from firmware, ice_aq_discover_caps, has potentially undesirable
side effects.
ice_aq_discover_caps calls ice_parse_caps, resulting in overwriting the
capabilities stored in the hw structure. This is ok during
initialization, but means that code which wants to read the capabilities
after initialization cannot use ice_aq_discover_caps without being
careful of the side effects.
Factor out the AQ command logic into a new ice_aq_list_caps function.
This will be used by the ice_aq_discover_caps function.

The ice_parse_caps function is used to convert the capability block data
coming from firmware into a structured format used by other parts of the
code.
The current implementation directly updates the hw->func_caps and
hw->dev_caps structures. It is directly called from within
ice_aq_discover_caps. This causes the discover_caps function to have the
side effect of modifying the hw capability structures, which is not
intuitive.
Split this function into ice_parse_dev_caps and ice_parse_func_caps.
These functions will take a pointer to the dev_caps and func_caps
respectively. Also create an ice_parse_common_caps for sharing the
capability logic that is common to device and function.
Doing so enables a future refactor to allow reading and parsing
capabilities into a local caps structure instead of modifying the
members of the hw structure directly.
