Lech Perczak 4d89918a98 ipq40xx: fix MAC address on Meraki MR33 and MR74 after nvmem-layout 
...conversion.
Commit 20736013e9 ("kernel: backport nvmem v6.6 fixes and v6.7 changes")
has caused dthe device to no longer correctly read MAC address from its
onboard 24c64 EEPROM, because "at24" driver doesn't support legacy
nvmem-cell bindings [1] - and there was an explicit config option added
to mandate that behaviour in the following patch:

820-v6.7-0002-nvmem-add-explicit-config-option-to-read-old-syntax-.patch

But some of the devices, MR33 and MR74 included, weren't converted with
that as well.
Convert the definition to use proper fixed-layout binding to fix it.

The offending change was introduced between v23.05.0 and v23.05.1, and
found by bisection:
