This commit extends the `mt76_connac_mcu_uni_add_dev` function to include
support for Multi-Link Operation (MLO). Additionally, backward
compatibility for MT7921 is preserved, enabling seamless integration with
existing setups.

DIV_ROUND_CLOSEST() after kstrtoul() results in an overflow if a large
number such as 18446744073709551615 is provided by the user.
Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.

When a client is roaming to a different AP interface, a duplicate wtbl entry
can be created. This can lead to lost packets or aggregation issues until
the old entry expires.
In order to fix this issue, delete any conflicting entries from WTBL
whenever a station is authorized.

It seems that the firmware checks the register used for detecting matching
PCIe links in order to figure out if a secondary PCIe link is enabled.
Write the register again just before starting the firmware on hw reset,
in order to fix an issue that left the second band unusable after restart.
