Add support for providing eeprom in nvmem cells by adding nvmem cell as
an alternative source for mt76_get_of_eeprom().
Nvmem cells will follow standard nvmem cell definition and needs to be
called 'eeprom' to be correctly identified.

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.

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

For some cases as below, we may encounter the unpreditable chip stats
in driver probe()
* The system reboot flow do not work properly, such as kernel oops while
rebooting, and then the driver do not go back to default status at
this moment.
* Similar to the flow above. If the device was enabled in BIOS or UEFI,
the system may switch to Linux without driver fully shutdown.
To avoid the problem, force push the device back to default in probe()
* mt7921e_mcu_fw_pmctrl() : return control privilege to chip side.
* mt7921_wfsys_reset() : cleanup chip config before resource init.

by chip fw problem. Migrate AP start/stop process to .start_ap/.stop_ap and

* AP start
.start_ap()
configure BSS network resource
set BSS to connected state
.bss_info_changed()
enable fw beacon offload
* AP stop
.bss_info_changed()
disable fw beacon offload (skip this command)
.stop_ap()
set BSS to disconnected state (beacon offload disabled automatically)
