Felix Fietkau 2c1a77c74f mt76x2: fix transmission of encrypted management frames 
Hardware encryption seems to break encrypted unicast mgmt tx.
Unfortunately the hardware TXWI header does not have a bit to indicate
that a frame is software encrypted, so sw-encrypted frames need to use a
different WCID. For that to work, the CCMP PN needs to be generated in
software, which makes things a bit slower, so only do it for keys that
also need to tx management frames.

Kristian EvensenandFelix Fietkau 2f40e4ad49 mt76x2: Support using PCI ID as chip ID 
On some routers, the manufacturer has made a mistake and left the chip
ID part of the EEPROM empty (it is set to 0x0000). One such router is
the ZBT-WE1026-5G (equipped with MT7612), and the consequence is that
the EEPROM check fails and the 5GHz wifi does not work at all. When
setting the chip ID to 0x7612 manually, the 5GHz wifi works fine.

When looking at EEPROM of the WE1026 (and other devices equipped with
mt76x2), I see that the PCI ID is always set to a valid value (7612 or
7662). This PR works around the issue of an empty chip ID by using the
PCI ID, if chip ID is 0. After applying this PR/patch manually to mt76,
the 5GHz on the WE1026 works out of the box. Since the PCI ID is only
used if chip ID is empty, devices with correct EEPROMs are not affected.
