I think it would be better to just do mt76x2e check like this:

        bool is_mt76x2e = mt76_is_mmio(dev) && is_mt76x2(dev);

        if (is_mt76x2e)
                mt76_rmw(dev, MT_MCU_COM_REG0, BIT(31), 0);

Then we will not have sparate calibration functions for mt76x2e and
mt76x2u, so code could be easier shared between those.

Thanks
Stanislaw
