Dan CarpenterandFelix Fietkau ded14da5ea mt76: mt7915: fix a precision vs width bug in printk
Precision %.*s was intended instead of width %*s.  The original code
will still print unintended data from beyond the end of skb->data.

Ryder LeeandFelix Fietkau cf0e406af8 mt76: mt7915: add support for applying pre-calibration data
When the EEPROM data is read from flash, it can contain pre-calibration
data, which can save calibration time.

Note that group_cal can save 30% bootup calibration time, and dpd_cal can
save 75% channel switching time.
