Add mt76x02_get_rx_gain and mt76x02_get_lna_gain utility routines
for rx gain parsing. mt76x02_get_rx_gain and mt76x02_get_lna_gain
will be reused for eeprom parsing in mt76x0 driver

Move mt76x2_eeprom_get utility routine in mt76x02_eeprom.h since
it will be used to parse mt76x0 eeprom in order to unify eeprom
support between mt76x2 and mt76x0 drivers

Add stbc tx power eeprom parsing support for mt76x2 driver.
When writing power entries, make a distinction between rates that are
read from the same EEPROM value, but have separate register entries.
No effect on runtime behavior, but preparation for unification with mt76x0
and for placing restrictions on individual rate power limits

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.
