495184ac91 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.

4efcfd5c36 mt76: mt7615: load ROM patch before checking patch semaphore status
For MT7663, the availability of the patch files is used to detect, which
corresponding firmware is going to be used (AP firmware or STA offload
firmware). If the ROM patch was already applied, it could attempt to
load the wrong firmware (without considering the alternative).

83216e3988 of: net: pass the dst buffer to of_get_mac_address()
of_get_mac_address() returns a "const void*" pointer to a MAC address.
Lately, support to fetch the MAC address by an NVMEM provider was added.
But this will only work with platform devices. It will not work with
PCI devices (e.g. of an integrated root complex) and esp. not with DSA
ports.

There is an of_* variant of the nvmem binding which works without
devices. The returned data of a nvmem_cell_read() has to be freed after
use. On the other hand the return of_get_mac_address() points to some
static data without a lifetime. The trick for now, was to allocate a
device resource managed buffer which is then returned. This will only
work if we have an actual device.

Change it, so that the caller of of_get_mac_address() has to supply a
buffer where the MAC address is written to. Unfortunately, this will
touch all drivers which use the of_get_mac_address().

Usually the code looks like:

  const char *addr;
  addr = of_get_mac_address(np);
  if (!IS_ERR(addr))
    ether_addr_copy(ndev->dev_addr, addr);

This can then be simply rewritten as:

  of_get_mac_address(np, ndev->dev_addr);

Sometimes is_valid_ether_addr() is used to test the MAC address.
of_get_mac_address() already makes sure, it just returns a valid MAC
address. Thus we can just test its return code. But we have to be
careful if there are still other sources for the MAC address before the
of_get_mac_address(). In this case we have to keep the
is_valid_ether_addr() call.

The following coccinelle patch was used to convert common cases to the
new style. Afterwards, I've manually gone over the drivers and fixed the
return code variable: either used a new one or if one was already
available use that. Mansour Moufid, thanks for that coccinelle patch!

BSS_INFO_BASIC is never called alone with inactive state, which always
follows beacon offload disable, so keep it enabled throughout interfaces
life cycle. Inactive state also removes sta record of all connected
stations, thurs causes connection lost which defeats the purpose of CSA.

Lastly, this is especially an unexpected behavior that keeping mt7622
failing beacon buffer recyled when scanning channels.
