Commit 495184ac ("mt76: mt7915: add support for applying
pre-calibration data") was fundamentally broken and never worked.

The idea (before NVMEM support) was to expand the MTD function and pass
an additional offset. For normal EEPROM load the offset would always be
0. For the purpose of precal loading, an offset was passed that was
internally the size of EEPROM, since precal data is right after the
EEPROM.

Problem is that the offset value passed is never handled and is actually
overwrite by

	offset = be32_to_cpup(list);
	ret = mtd_read(mtd, offset, len, &retlen, eep);

resulting in the passed offset value always ingnored. (and even passing
garbage data as precal as the start of the EEPROM is getting read)

Fix this by adding to the current offset value, the offset from DT to
correctly read the piece of data at the requested location.

To diagnose the reason why firmware or hardware get abnormal, add to dump
MAC registers related to counters and interrupt masks. With these values,
people can classify problems and check if registers values are unexpected,
and then correct them. However, it could possible false alarm because
firmware triggers this SER event by wrong conditions that we should
correct it at firmware or register settings.

In field, SER might happen under special conditions, and very hard to
happen again, so dump lots of registers to provide rich information to
catch the problem.

In concurrent mode, when STA interface is scanning, it causes

with the operating channel when one of the interfaces is already
connected. Additionally, STA interface need to stop scan when AP
interface is starting to avoid TX beacon on wrong channel. Finally,
AP interface need to stop TX beacon when STA interface is scanning
and switching to non-OP channel,This prevent other device to get

We add a scanning check to avoid entering IPS after ROC (remain on
channel) during scanning. Additionally, When P2P scanning, the flow is
`1. p2p_listen step` and `2. configure filter` and `3. p2p_scan starts`
in wpas, but in kernel, cfg80211 uses another workqueue to notify driver
the filter change, so sometimes we see (1 > 3 > 2), that will cause Rx
filter related to scan to be cleared. Therefore, we add a scanning check
when configure filter to avoid scan results to be filtered. Finally, we
cancel the ROC delayed workqueue before entering ROC to avoid entering
twice, which might cause leaving ROC too early.
