ice: add 1G SGMII PHY type

There isn't a case for 1G SGMII in ice_get_media_type() so add
the handling for it.

Also handle the special case where some direct attach
cables may report that they support 1G SGMII, but
that is erroneous since SGMII is supposed to be a
backplane media type (between a MAC and a PHY). If
the driver doesn't handle this special case then a
user could see the 'Port' in ethtool change from
'Direct attach Copper' to 'Backplane' when they have
forced the speed to 1G, but the cable hasn't changed.

Lastly, change ice_aq_get_phy_caps() to save the
module_type info if the function was called with
ICE_AQC_REPORT_TOPO_CAP. This call uses the media
information to populate the module_type. If no
media is present then the values in module_type
will be 0.

ice: add link lenient and default override support

Adds functions to check for link override firmware support and get
the override settings for a port. The previously supported/default link
mode was strict mode.

In strict mode link is configured based on get PHY capabilities PHY types
with media.

Lenient mode is now the default link mode. In lenient mode the link is
configured based on get PHY capabilities PHY types without media. This
allows the user to configure link that the media does not report. Limit the
minimum supported link mode to 25G for devices that support 100G, and 1G
for devices that support less than 100G.

Default override is only supported in lenient mode. If default override
is supported and enabled, then default override values are used for
configuring speed and FEC. Default override provide persistent link
settings in the NVM.

If the OS package version is not compatible with NVM then return an

Split the 32-byte segment name into a 28-byte segment name and
a 4-byte Track-ID. Older packages will still work with this change
because no package has a name that will take up more than 28 bytes;
in this case the Track-ID will be 0.

Note that the driver will store the segment name as 32-bytes in the
ice_hw structure, in order to normalize the length of the various
package name strings that it uses.

Also add section ID and structure for the segment metadata section.

ice: discover and store size of available flash

When reading from the NVM using a flat address, it is useful to know the
upper bound on the size of the flash contents. This value is not stored
within the NVM.

We can determine the size by performing a bisection between upper and
lower bounds. It is known that the size cannot exceed 16 MB (offset of
0xFFFFFF).

Use a while loop to bisect the upper and lower bounds by reading one
byte at a time. On a failed read, lower the maximum bound. On
a successful read, increase the lower bound.

Save this as the flash_size in the ice_nvm_info structure that contains
data related to the NVM.

The size will be used in a future patch for implementing full NVM read
via ethtool's GEEPROM command.

The maximum possible size for the flash is bounded by the size limit for
the NVM AdminQ commands. Add a new macro, ICE_AQC_NVM_MAX_OFFSET, which
can be used to represent this upper bound.

ice: create function to read a section of the NVM and Shadow RAM

The NVM contents are read via firmware by using the ice_aq_read_nvm
function. This function has a couple of limits:

1) The AdminQ commands can only take buffers sized up to 4Kb. Thus, any
larger read must be split into multiple reads.
2) when reading from the Shadow RAM, reads must not cross sector
boundaries. The sectors are also 4Kb in size.

Implement the ice_read_flat_nvm function to read portions of the NVM by
flat offset. That is, to read using offsets from the start of the NVM
rather than from a specific module.

This function will be able to read both from the NVM and from the Shadow
RAM. For simplicity NVM reads will always be broken up to not cross 4Kb
page boundaries, even though this is not required unless reading from
the Shadow RAM.

Use this new function as the implementation of ice_read_sr_word_aq.

The ice_read_sr_buf_aq function is not modified here. This is because
a following change will remove the only caller of that function in favor
of directly using ice_read_flat_nvm. Thus, there is little benefit to
changing it now only to remove it momentarily. At the same time, the
ice_read_sr_aq function will also be removed.

ice: Handle LAN overflow event for VF queues

Currently we are not handling LAN overflow events. There can be cases
where LAN overflow events occur on VF queues, especially with Link Flow
Control (LFC) enabled on the controlling PF. In order to recover from
the LAN overflow event caused by a VF we need to determine if the queue
belongs to a VF and reset that VF accordingly.

The struct ice_aqc_event_lan_overflow returns a copy of the GLDCB_RTCTQ
register, which tells us what the queue index is in the global/device
space. The global queue index needs to first be converted to a PF space
queue index and then it can be used to find if a VF owns it.
