Setting MT_TX_ABORT does not abort any transmission for a wtbl index on its
own. Instead, it modifies the behavior of a queue flush to make it selectively
flush packets for a particular wtbl index.
Adjust powersave filtering to make use of this in order to avoid running into
unnecessary timeouts while flushing

All kind of calibration data should be described as NVMEM cells of NVMEM
devices. That is more generic solution than "mediatek,mtd-eeprom" which
is MTD specific.

Add support for EEPROM NVMEM cells and deprecate existing MTD-based
property.

Add support for providing eeprom in nvmem cells by adding nvmem cell as

In preparation for NVMEM support, split get_of_eeprom() in subfunction
to tidy the code and facilitate the addition of alternative method to
get eeprom data. No behaviour change intended.

While at it also drop OF ifdef checks as OF have stubs and calling
of_get_property would result in the same error returned.

* AP stop

    .stop_ap()
